I'm selling my Yamaha PB-1 preamp because I'm now using a GB 600. Most will know this as probably the best buy around for a SS preamp or probably any preamp. Sounds really warm, lots of tonal options, also good if you want to run highs to one cab and lows to another. Balanced output with on-off ground and level, parametric EQ and separate treble mids and bass. Read up on this and you will only find excellent reviews. I've had this about 4 years and never had any problems. Used every week for practice for about 2 years and its seen maybe a dozen gigs. I always had it racked. Front panel in very good condition. There are a lot of scratches on the top and bottom, which were there when I bought it. Since I only used it racked they were not really an issue. I'll take $150 including shipping and paypal fees. Thanks.
