I busted the budget for a new toy – the TC Electronics G Natural. I’ve been using a simple Boss DD-3 Digital Delay for my only effect, running into either a Fishman Performer Pro amp or a PA based on an old Peavey XM-6 mixer amp. I’ve never been too thrilled with my amplified sound, so I’m starting the process of (hopefully) upgrading.

The new G Natural is a floor box with big sturdy stomp switches controlling a collection of pristine effects with a clever system for storing user settings. The box includes routing for a microphone, pickup, and line inputs, but there are some limits on how these can be combined.

I’ve been working around home with the G Natch, and I’ve used it on two gigs, so I’m beginning to get a handle on the major features and capabilities. I’m sure it will reward a lot of study and tweaking, but I’m ready to pass along some first impressions even though they’re preliminary.

I made a big goof when I first began using this device. The input gain setting is buried in the levels menu, and in the “preliminary” manual that came with my unit did not have the correct information for the unit I received, so I did not understand the importance of the “Input Gain” setting. Instead, I used too much gain to boost the ouput from the G Natural, and the result was a lot of hiss. After a day or so of frustration I discovered the correct setting, then I found the updated manual online at the TC site, and since then I’ve been extremely impressed with the sound quality and low noise of the unit. So kudos to TC for creating such a high quality box, and lemons for shipping the unit with an incorrect manual.

Even with the updated manual the information is fairly skimpy, and the organization is a bit less than ideal. But since the book (actually a PDF) is so short it’s not too big a challenge to read the whole thing a couple of times and gradually pull the pieces together.

One question I had before working my unit – can the G Natural be used as a DI or Direct Input device. A DI is a device which takes a 1/4″ high impedance unbalanced input, like a guitar pickup, and converts the signal to a balanced low impedance output on a male XLR connector. This is very handy for stage use because low impedance balanced cables can be run for long distances without signal loss or noise buildup. DIs are also used in the studio for connecting bass, guitar, or other unbalanced signals to balanced mic inputs.

Since the G Natural has a male XLR on the back, it might seem that this is a DI output, but that is not the case. This connector will only deliver the signal connected to the Mic Input, not the signal connected to the instrument input. So the simple solution won’t work. However, the 1/4″ outputs are balanced, which means that a simple adapter cable can be bought or made to provide DI functionality from the main outputs. HOWEVER, TC warns that these outputs should not be connected to an input providing phantom power. This is important, and easy to overlook. On your own mixing board, you’ll probably check phantom power and turn it off as needed, but if you’re working with various sound engineers in various venues, the chance for a mistake may be too high. And in some PA mixers, the phantom power cannot be controlled for individual channels, so this limitation may lead to other problems. In other words, I think I’m going to buy a DI to add to my signal chain before I connect the G Natural to a PA other than my own.

A look through the manual will show that all the effects needed for enhancing an acoustic sound are present – compression, eq, modulation, delay, and reverb. The unit also features a “one click” boost feature that simply raises the level for solos. Notice that there is no distortion effect included – if distortion is part of your acoustic sound, you’ll probably want a different multi-effects unit.

Finally, here are some samples. I played each clip separately, so there are plenty of performance variations. The guitar is a Martin OM-18GE with a K&K Pure Western pickup.

I miked the guitar with a Shure KSM141 set flat, cardioid pattern, about 6″ from the 12th fret, through a John Hardy M-1.

Here’s the direct pickup sound, through an M-Audio DMP3.

The pickup through the G Natural, all effects bypassed (setting F9-3).

Something on the wild side, F4-3, Clean Cowboy.

F5-3, Clean Chorus.

I’ve created a few user settings, here’s the one stored at U0-2.

Next time I’ll talk about the stompbox-edness of the G Natural. There are lots of useful variations to be had by stepping on the big chrome buttons.

Just before we left for Hawai`i in April, I received my handmade Go Type II Parlor guitar from Sam Radding at Go Guitars. You can see some clips of this little instrument in action at my Kaleponi Music News blog.

For the last few years, I’ve checked my full size guitar in a Calton case, but I really enjoy having a guitar with me during those long airport waits. When I learned that Mr. Radding would build one of his parlor guitars with a custom neck shape and bridge spacing, I signed up. His guitar turned out to be a great success, small enough to fit in the airliner overhead compartment, good enough to play on stage at the Royal Hawaiian Hotel.

When we returned from our trip, I contacted Matt Hayden to see if we could get together to compare his Larrivee Parlor to this new one. Matt’s guitar is walnut and sitka, just like the Go, so the comparison seemed like a natural.

Here are some pics showing the two guitars side by side.

The Larrivee is several years older, so the sitka spruce top has mellowed to a lovely shade. The smaller body of the Go is evident in this shot, as is the compact headstock and lesser overall length.

Looking at a closeup of the backs, I prefer the walnut back of the Larrivee with its slight curly figure and darker finish, but many people commented favorably on the interesting figure of the Go walnut. The bookmatch on the Go two piece back is nicely done, and the backstrip adds a little appeal as well.

This side by side shot illustrates the shorter body and longer scale of the Go. I think it’s amazing that Mr. Radding has squeezed so much guitar into such a diminuitive shape.

I plugged a DPA 4061 mic into my Marantz PMD670 recorder and played a verse of “Kui Lima” on each guitar. Here’s the Larrivee sample (link). The Go sounds like this (link). In person, the Go seemed a little fuller and a bit louder. In fact, everyone who tried the Go so far has expressed amazement at the amount of sound that pours out of this tiny guitar.

As far as playability, the comparison is a bit unfair. I owned a Larrivee similar to Matt’s but sold it because I had a hard time with neck shape and bridge spacing. One of the great advantages of the Go Parlor is the availability of custom neck shape and bridge spacing. The slightly wider neck and bridge on my Go Parlor makes all the difference in ease of playing.

The first generation of Larrivee Parlors, like Matt’s, were built as style 01 Larrivees, which means they were stripped down models. They were also a wonderful bargain. But these days Larrivee only builds these guitars with style 09 trim. They’re much more nicely finished but cost over twice the price of the older model. The Go, which is handmade and available with custom features, is a terrific value and a very fine way to carry your music with you wherever you go.

On the acoustic guitar forums I visit, one common question goes something like:

How do I record my guitar so I can judge my progress (or lay down a rhythm track or even make a CD just for family and friends). I have a pickup in the guitar, I don’t need great quality, and I don’t want to spend a lot.

Since this person is posting on an internet forum, I will assume they have a computer. If it’s a PC type, it almost certainly has some kind of built-in soundcard, with at least a mic input. So all we need to do is hook the guitar pickup to that mic input and use some sort of program to capture that input and save it to a file. It just so happens that there are some very effective recording programs available to download for free, so that leaves as our only problem some way to connect the guitar pickup to the mic input. And here it is:

This is a 1/4″ phone female to 1/8″ mini male adapter. A normal guitar cable like the one just above the adapter in this picture (male 1/4″ phone plugs at both ends) fits into the hollow side. The pointed side plugs into the mic input of the computer. It costs about $4.00 at any store or web site that sells electronic geegaws (like Radio Shack). This is all you need to connect your pickup to your computer (assuming you have a guitar cable).

Now, on the software side what are the options? Unfortunately, the built-in Windows Sound Recorder is not very useful. It’s limited to about 1 minute of continuous recording without intervention. There are not effects or editing features, no click track or metronome, no metering, and certainly no multitrack overdubbing and mixing.

The easiest free program I’ve found is Audacity – it’s a little clunky but it is full featured. It includes plenty of editing capability and built-in effects, and you can save your recordings to various formats like .wav for burning to CD and (with some free extra software) to .mp3 for your portable music player or web site. I’ve used this little adapter and Audacity to record new song ideas on our laptop when we’re traveling. I’ve also used it to create practice loops when I’m trying to nail a tough section of a new song. Compared to a decent microphone, preamp, and audio interface these recordings are fuzzy, noisy, and crude, but they do the job, and the price is definitely right.

Here’s one verse of an old Hawaiian song, “No Ke Ano Ahiahi,” recorded as a solo guitar instrumental using the the 1/8″ mini plug adapter and Audacity.

And here’s the same track with some reverb added.

Obviously these are not “major label quality” recordings by a long shot. The direct output from a pickup is not very close to the natural acoustic sound of your guitar. But we’ve looked at a tool that can help get your pickup based recordings much closer to a natural acoustic sound in a previous blog entry: “Better EQ Through Software”. And, as we stated at the beginning of this entry, the whole purpose of using this simple, cheap adapter is to get simple, cheap recordings, not Grammy awards.

This past sunday I performed at Pacific Bay Coffee Company here in Walnut Creek. As always it was an enjoyable experience.

Since I just snagged some new mics on Ebay I decided to try them out as live performance tools. The mics are a pair of Electrovoice RE16 dynamic hypercardioids. These mics have the “Variable-D” feature that reduces proximity effect.

I used one RE16 for my vocal introductions and the other pointed at the bridge of my Martin OM-18GE. The mics were plugged into my very modest Peavey powered mixer, which was driving one pole-mounted Klipsch Heresy speaker.

I also recorded the show, using the tape out jack on the Peavey to feed the line in connectors on my Marantz PMD-670.

The results were interesting. It took a lot of attention to keep from bumping the guitar into the mic. I’ll probably try moving the mic to the 12th fret area, next time. The audience seemed happy with the balance and volume, but on the recording the guitar is pretty quiet, and the typical coffee shop background noises are pretty loud. I did think the tonal quality of the recording was pretty acceptable, and I’m looking forward to trying some “studio” tests with these mics.

In the meantime, I put two of the tunes from the Pac Bay show up at the Kaleponi.com Music Page.
