The legendary, grey Ross Compressor is quite popular at the moment, although probably only few have ever used it.
Initially, Ross effects were pretty unfamiliar.
But as Trey Anastasio (Phish) once discovered the Ross Compressor for himself, it became popular.
The Ross Compressor has been developed in the late 70s.
Its circuit is based on the MXR Script Dyna Comp which has been optimized a little bit.
Because of its smoother sound and the fact, that only few pedals have been produced, the Ross Compressor became a famous and sought-for vintage effect.
At the time when the Script Dyna Comp has been altered to the Block Logo Dyna Comp (and by this also git new transistors), the Ross Compressor took up the sound and the components of the Script model.
The circuit is based on an OTA, the compressor creates much sustain, a mid/treble boost and cuts the low end.
Therefore, to many guitarists, the Ross Compressor is the perfect compressor as a solo boost.
For quite some time, there are numerous good compressor pedals that are based on or at least emulate the Ross Compressor.
The most famous ones are the Analog Man Bi-Compressor and the Keeley Compressor.
By an additional “mix” pot, the Xotic SP and the Barber Tone Press allow to add the original and uncompressed signal to the compressed one.
But many other compressor pedals are more or less geared to the circuit of the Ross Compressor (Cmat mods, Wampler, BYOC), though there are offerings in every price category.
Recently, the brand Ross has been recalled to life and one of the first pedals being reissued is the Ross Compressor.
Handmade in the USA this reissue prevails the well-known design with true bypass.
In favor of its original design, the Ross Compressor reissue dispense with a “blend” pot which many current compressor pedals offer to control the uncompressed signal.
The expectations are high if the reissue revived the legendary original not only optically and if it is able to compete with the sound of its boutique successors.
