I discovered Tech21 when I bought a bass driver pedal and ran it into mt Carvin Redline R 1000 head . The head was versitile and had a lot of power but when I put the Sans Amp into it I knew I had the tone I wanted . I used that for a while but found it hard to make adjustments on crowded stages with the pedal on the floor . When the RBI preamp came out it was just what I wanted with the bonus of a mid control , I loved it with the Carvin head as a power amp . I switched to Crown power later and gigged with that for a few years . Sound guys loved the DI out and I was happy too . I later switched to an Ampeg SVPCL tube preamp but the RBI remained one of my favorite preamps .
Pro level for sure .
