Barge Concepts' DB-3 is a new high accuracy, linear amplifier with two independent channels that each have individual gain and volume controls and an effects loop between the two channels. Both channels also have high input impedance ins and low output impedance outs as well as true bypass.

The DB-3's channel duo can be directly cascaded, or you can use the effects loop to separate the channels and place a boost or a buffer at two points in the signal chain. When the channels are cascaded, four different volume levels are attainable. The effects loop is set up like an amp's effects loop. When there are no pedals in the loop, the output of Channel 1 goes directly into the input of Channel 2. When pedals are in the loop, the output of Channel 1 is sent to the pedals and then through the pedals to Channel 2's input. The send output from there is always active, which is perfect to go into your tuner or a second amplifier.

The DB-3 can also be used as an overdrive / distortion pedal at any output volume. When the cascaded gain stages and Master Volume are used in combination, the DB-3 clips sharply yet cleanly and symmetrically with no phase inversion or any undesired sounds. However, the DB-3's main purpose is to act as a boost that does as little as possible to alter the original signal aside from making it louder.
