The Rocktron Utopia G300 is a professional guitar system in floor processor form: a multi-effects unit you operate with your feet, with a built-in expression pedal, amp-style channels and a full effects section in one metal chassis1. Rocktron describes the Utopia G Series as putting "Incredible tone and awesome sounding effects... at your feet"1. It is part of the wider family of multi-effects pedals, and sits alongside Rocktron's rack units such as the Prophesy and the Chameleon On-Line.
Sound and channels
The G300's amp voicings come as four channel selections: Clean, Texas, British and Mega1. Rocktron's page presents these as the tonal foundation of the unit, with the names pointing at familiar clean and gain territories. Pre-effects include wah, phaser and compressor, placed before the amp voicing in the chain2. The unit runs on a Motorola 24 Bit DSP engine with AKM converters, which handles the processing for both the channels and the effects1.
The controls and footswitches
The G300 is built to be driven entirely from the floor. Its footswitch system works in two modes: Up/Down preset bank switching by 10 with instant recall buttons, and a second mode with 10 instant access controller switches for turning effects and functions on and off directly1. An easy-to-read Cool Blue LCD display shows you where you are in the preset and editing process1.
The built-in expression pedal is a roadworthy professional grade unit made from metal, and there is also an extra external expression controller pedal port if you want a second pedal for more parameters1.
| Control | What it does |
|---|---|
| Up/Down bank buttons | Move through presets in banks of 10 with instant recall1 |
| 10 instant access switches | Second mode: direct control of effects and functions1 |
| Built-in expression pedal | Metal, professional grade real-time control1 |
| External expression port | Adds a second expression controller pedal1 |
| Cool Blue LCD | Easy-to-read display for presets and editing1 |
Presets
The G300 holds 128 presets in total, split into 64 factory presets and 64 user presets1. Rocktron's page also describes the 128 as user programmable, so the factory side can be replaced with your own sounds1.
Connections and power
The rear panel carries a 1/4" mono input jack, stereo outputs, MIDI in and MIDI out/thru, and a heavy duty headphone output on a 1/8 stereo phone jack12. There is also an auxiliary input (1/8 stereo phone) for an MP3 player, CD player or iPod, which makes the G300 usable as a silent practice rig with backing tracks1.
The G300 runs on 9VAC at a minimum of 2.9 amps2. This is an AC requirement, not the 9V DC center negative standard of most compact pedals, so it cannot share a typical pedalboard daisy chain and needs its own supply.
Physically, the unit measures 20 1/4" wide by 9" deep, with the height changing from 3 1/4" with the expression pedal toe down to 4 7/8" with the toe up (510mm x 228mm x 83mm to 124mm), and it weighs 8.5 lbs (3.85 kg)2. The whole thing is built into a rugged metal chassis1.
