With a high-quality preamp, dual effects section, tone controls, a compressor, level booster and a balanced DI - the ToneDEQ has everything you need in one box. Its analog signal path goes from end to end – from preamp to output – to give acoustic musicians a richer tonal quality. Even the digital effects are mixed in parallel so they don’t affect the purity of the your acoustic instrument. Fully Balanced Stage DI Flexible outputs include a 1/4" amplifier output and XLR DI output for the lowest noise possible. Plus the DI features automatic ground-lifting and selectable pre/post EQ settings. Discrete Class A Preamp With Fishman, you get quality discrete Class A signal conditioning created by a leader in instrument preamp design. The high impedance input is a must for any passive instrument pickup. Advanced 4-Band EQ Legendary 4-band equalizer design provides superior tone control for any acoustic instrument. The variable low cut filter controls sub-bass effects produced by some passive pickups.
