Haven’t tried it yet, but did mega online research for best Spring for surf and decided on this. There was one that actually might have been a tad better, but it was 50 bucks more and had a computer-connection dealie which turns me away usually. Anyhow, it’s going in the effects loop of my still-untried Quilter Tone Block 201. They’re both waiting for the darn cab, which finally shipped today. Surf’s up, dudes and dudettes!
