The Karen by Vemuram is a discontinued Marshall type overdrive-distortion pedal designed to recreate the tone of the mid 70's to early 80's Marshall amps, such as the 4 input JMP and the 2 input JCM. It offers a rich and full sound with natural compression and a thick saturated tone without any high-end loss. The technical specifications for the Karen by Vemuram are as follows:
- Transistors: N/A
- Controls: Level, Gain, Tone / Gain Control Trimmer
- Switches: ON/OFF
- Terminal: Input, Output
- Power: 006P (9 Volt Battery) or 9 Volt regulated AC/DC adapter (Center
Negative)
- Size: 70(W) x 113(D) x 50(H)mm
- Weight: 425g
- Current Draw: 6 mA
- All pedals are compatible with 18V except for fuzz pedals, but it is
designed for 9V, and using higher voltages is not recommended.
The Karen is designed to provide the warm natural power of the late 70s to early 80s Marshall sound, capturing the fat drive tone and thick saturation of classic JMP or JCM amps, complete with natural compression and well-preserved higher frequencies.
