I'd normally be very sceptical if somebody said they'd come up with an all-analogue pedal-sized preamp that could emulate not only the tonal coloration but also the power stage harmonic characteristics of a particular valve amplifier
DACS reformatted this classic preamp in 2011 to fit the API 500 series ‘Lunchbox’ modular format but it's only now that Hugh has found time to check it out.
With user-configurable valve stages, the option of transformer-coupling and more besides, Sonic Farm’s preamp provides a broad palette of tonal options.
ART's Tube MP/C combines a hybrid 12AX7 (ECC83) valve preamp section with the company's 'Vactrol' optical compressor, and the whole thing is all about tonal character.
