Master Effects Super Fifty Ashly SC-50 Compressor Limiter

NOTE: THIS PEDAL CAN TAKE UP TO 10 DAYS TO SHIP. ALL PARTS IN STOCK, JUST NEEDS TO BE ASSEMBLED.

The Super Fifty is our interpretation of the legendary vintage Ashly SC-50 Peak Limiter/Compressor rackmount unit.  This pedal, like the SC-50, is a line-level operating device.   If using this with instrument level signals then a preamplifier must be used to bring the signal up to line levels otherwise the pedal may not operate as expected.

​There are 5 controls: Gain, Ratio, Attack, Release and Output.  A toggle switch engages the limiter portion of the circuit.

​​

The pedal uses a standard boss-style 9V power supply with an internal SMPS that generates ±15V to run the pedal. This is the equivalent of running the pedal with a 30V supply giving plenty of headroom. We use SMD JRC4558 and LM301 op-amps throughout the pedal.  We also use high tolerance 0.1% resistors and transistor arrays for the gain matching in the limiter circuit as well as transistor arrays to ensure the absolute best conditions for matching the gains in the VCAs.

​

Each pedal uses a professionally assembled 4-layer PCB to minimize noise and is proudly assembled by hand in Calgary, Alberta, Canada.

​

Each pedal comes with a 1 year warranty on parts and labour. Note that the warranty does not cover damage due to using an improper power supply or other misuse.
