What's currently out there , preferably not in a 19" rack and NOT meant for overdriven/distorted tones (natural tube compression is a must though !) ? I know of the Kingsley "Squire/Minstrel" pedals (currently unavailable), the Demeter Mighty Minnie (it has a power amp built-in, don't need that) and the Sarno products. Alembic comes to mind but these were built for bassists mainly and the sound is rather bland and hi-fi .... I play mainly Jazz/Soul/Funk gigs and when I want grit I kick in a pedal. For recording purposes the preamp would be used in combination with a high quality cab-simulator. Please let me know !
