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.
