Deciboost

Alex G. Lim Signature Edition Clean Boost

Up to 22dB of crystal-clear boost—seamlessly activated via your volume knob. Refined with Alex G. Lim for maximum ease of use.

This edition of the Mars-Tronic Deciboost was developed in collaboration with Alex G. Lim, bringing enhanced functionality to an already trusted design. Featuring a discreet push/push volume pot, the boost is always within reach—no extra switches, no pedal required.

First featured in Guitarist Magazine with PJDs Andy Summers Tribute Carey Custom, the Deciboost circuit gained recognition for its clarity, headroom, and responsiveness. The Alex G. Lim Signature Edition keeps all of that—and puts ease of use at the fore, with refinements shaped by real-world stage feedback.

Once engaged, this dynamic gain tool, lets you dial in the exact level of boost in real time. The internal trimpot sets your maximum gain anywhere from 0dB to 22dB, giving you full control over how far it goes.

Key Features:

• Fast Activation: Push/push volume pot allows instant access to boost—no slipping, even with sweaty hands.
• Dynamic Control: Use your volume knob to fine-tune the boost level on the fly.
• Adjustable Max Gain: Internal trimpot sets range from 0dB to 22dB.
• True Bypass: Zero tone loss when disengaged.
• 9V Power: Standard 9V operation. Compatible with stereo jack auto-disconnect wiring.
