  1. Didn’t the market yawn at this product or something remarkably similar in the early 90s? It’s like those Aspri mechanical reverb units for acoustic guitars that failed on the market about the same time and are now back.

  2. This looks like a wonderful device. I particularly appreciated the musicality of the demonstrations. Thanks to Michael Ross (Guitar Moderne) for spreading the word on the Hammer Jammer. I will be ordering one very soon.
