Keeley Abbey Chamber Verb – Vintage Reverb Guitar Effect Pedal

$ 149.00

An echo room chamber is a space where program material is played and the reverberations are captured on a microphone.  You know the classic sounds of a good church or music hall. Studios needed to capture these effects without always going to a church or hall to record. So, they built their own echo chambers. The famous EMI/Abbey studio had 3 echo chambers. They also used electronic filters to carefully refine the sound in order to make it easier to record, which made the end results sound impeccable.

We have incorporated the RS106 filter which had points at 600Hz high pass filter and a 10K low pass filter. In the studio, music (or your guitar) was filtered through at these points before being sent to the speaker in the echo chamber. This made for a tighter, more defined sound to be present in the chamber.

Next there is the Brilliance Control, either the RS127 or RS135. This was what the engineers used to refine the reverb sound that they captured on the microphone. Engineers could select one of 3 frequency points to boost or cut by +/-10 dB. The key frequencies they targeted were 2.7 kHz, 3.5 kHz, or 10 kHz, now offered on the Abbey Chamber Verb.
