I'm currently using an ADA MP-1 Classic, but the occasional glitch has caused me to question it's long term reliability, so I'm looking at other options. I'm sure this has been asked a thousand times, but what current preamp offers the ultimate in versatility ranging from Tweed and Blackface Fender all the way through modded Marshall Plexi tones? No Recto required, just the classics. Budget is around $1200.
