"Almost Every Guitar Effect in One Pedalboard"

Having a Marshall Stack and array of boutique effects pedals for your guitar seems to be the ideal way to go to get that immaculate guitar sound. The problem is that unless you have roadies attending to your every whim, bringing your 4x12 cabinet, JCM800 head, your set of pedals, patch cables, etc. is a logistical nightmare. It’s always best if you can just plug in right away get the sound that you want through any amp that’s available wherever it is you’re playing. The Zoom G92tt has provided that answer.

One of the most attractive features of the Zoom G9.2tt is the presence of two 12AX7 tubes. Zoom designed each of the tubes to function differently, with one being in the “accelerator” section and one in the “energizer“ section. It seems to me that the “accelerator” section is the preamp while the “energizer” section serves to emulate the sound of a power amp, especially when the pedal is used as an audio interface. The “accelerator” can amplify a guitar signal through a tube circuit or a solid state circuit and even blend both. The energizer section has a knob controlling tube gain and a boost control for added highs and lows. All in all, both the “accelerator” and “energizer” sections provide a wonderful palette of tones for all sorts of musical applications such as a warm jazz tone, a crystal-clear solid-state clean, saturated tube distortion for metal, and others. The analog-style controls provide that real-time control and feel that users of analog pedals have always appreciated.

UTILIZATION

There are a number of amp simulations available in the Zoom G9.2tt ranging from emulations of Marshall JCMs and Mesa Boogies to cleaner sounding Fender and Roland Jazz Chorus imitations. You can assign two amp sims per patch, and one can switch between each amp sim using the A/B switch. The amp can be also be switched off or bypassed via the pre-amp switch. Each patch can host a chain of up to four kinds of effects: wah/EFX1, modulation/EFX2, delay, and reverb. These effects are obviously used to shape the sound further than what the two 12AX7 tube circuits and their controls can provide . While the default mode of operation is in patch mode i.e. each patch having a unique chain of amps and effects, it is also possible to operate in a more analog style using the manual mode. In manual mode, each switch acts as an on and off switch for every kind of effect along the effect chain assigned to a particular patch.

The Zoom G9.2tt has two assignable expression pedals, one on each side of the unit. The left expression pedal usually functions as a volume pedal by default. Because the left pedal is assignable, it means that it controls parameters digitally. The downside to this is that when switching patches, the Zoom G9.2tt goes to the patches default setting rather than keeping the supposed volume level as suggested by the pedal. I do think that it would have been best to have assigned the left pedal to control the Zoom G9.2tt’s master volume instead of being assignable. The right expression pedal has what’s called a Z-axis function. While the left pedal only moves up and down, the top part of the right pedal can be swiveled left and right, enabling users to control two parameters with the right pedal. For example, you can assign a wah for the standard up and down portion while assigning a pitch shifter for the Z-axis pedal. The right pedal is in effect two expression pedals stacked together!


SOUND QUALITY

Zoom G9.2tt is a multi-effects pedal, audio interface, and MIDI foot controller all rolled into one package. This is one of the reasons why I bought this unit in the first place. I have been using the Zoom G9.2tt for the past 9 months for both studio and live work primary as a guitar effects processor. It’s of great benefit that I can choose to record guitar using the pedal itself as an audio interface. It can record at a 16-bit/48-kHz resolution, sufficient for recording guitar parts using any DAW software. The Zoom G9.2tt can also be set up as a MIDI foot or pedal controller. The unit can send and receive MIDI messages through its MIDI in and out ports. For example, you can control switching scenes or loops on and off in Ableton Live or control virtual guitar amp software like Guitar Rig or Amplitube using the Zoom G9.2tt and a USB-to-MIDI cable.

OVERALL OPINION

The Zoom G9.2tt is a very versatile pedal that can offer all sorts of guitar tones you might want in a single package. It certainly is more convenient than bringing in a bunch of pedals, an amp head, and a speaker cabinet to a gig. Matter of fact is you can just plug your guitar to the Zoom G9.2tt, plug it’s output to any amp or PA that is available at the venue where you’re playing, and then just start rocking out. The sturdy metal casing coupled with rubber contact surfaces provides a good degree of comfort that it will withstand many gigging situations. I do think, however, that the pedal can be better if it had a looper, something seen in other multi-effects pedals like those released by Digitech. All in all, I do think it is one of the best multi-effects pedals that I’ve ever used.

Pros:
- Multipurpose functionality
- Tonal flexibility care of “accelerator” and “energizer” circuit
- Choice between patch and manual modes
- Two expression pedals (one standard, one Z pedal)
- Over 100 kinds of effects and amp simulations available

Cons:
- No looper function
- Volume reverts to normal assigned level after switching patches rather than staying at volume suggested by volume pedal position
