The Acoustic GiG multi-effects pedal begins with Carl Martin’s Compressor/Limiter circuit. Individual controls for compression and level allow for simple and easy operation. Next is the well-known and highly respected Vintage Style Echo, with controls for level, tone, repeat, and tap-tempo, plus the Dotted 8th Note switch for a beautiful musical echo. The Reverb is a new Analogue/Digital Hybrid, tailored after the vintage-style spring reverbs suitable for guitar. It’s a beautiful, shimmering, yet warm reverb with the bonus of becoming a more modulation/chorus/reverb texture at higher settings. The Boost simply allows you to cut through the mix with a crystal-clean volume increase of up to 15dB for solos. No change in tone, and no increased “quackiness” from your pickups.

To gain maximum EQ shaping, Carl Martin found it necessary to include a high-quality semi-parametric EQ. Carl Martin incorporated this section directly from his famous 3 Band Parametric Pre-Amp, which allows for the specific shaping of tone from your guitar and pickup. To avoid potential feedback, practice has shown the use of a phase inverter circuitry to be very efficient. So, of the Acoustic GiG has a Phase Shift switch. To complete the Acoustic GiG, Carl Martin has incorporated a tuner and an overall mute switch. On the back panel are all the needed connections: 1/4" input, unbalanced 1/4" output, high-quality balanced XLR out with ground lift, an insert section placed right after the boost and before the EQ section, and 9V DC input with a direct DC output if you find the need for an extra pedal.
