After developing the original Tone Block 200, Pat Quilter wanted a more complete "stand-alone" amp that could be used with or without a pedalboard. Most players like a nice built-in reverb, so the Pro Block 200 adds our nicely voiced reverb section as well as our Limiter to provide more control over the internal overdrive. The result is a fully featured amp, with or without external effects, that mates with our growing line of BlockDock speakers.
Best amp I've ever owned. Has it's own sound...a very good sound. Very adjustable TriQ, subtle but effective. Lately playing straight in with no pedals...old school....love the results. Used the direct out alot, very handy. Sound engineers love it. So do I.
My main amp for a long time... alternating between this and the Mach2-8. Both which replaced my tube amps. And was using this with the Celestion BN-300S speaker which sounds huge. The ProBlock took in all the pedal I put in front of it. Eventually replaced it with the TB202 and the SuperBlock US/UK as I'm going for a silent stage setup. Nothing wrong with the amp but since I had the TB202, I decided to sell it to spread the experience to others on how good Quilter amps sounded.
