Ron Holmes, the outstanding amp tech who built my customized Crate VC508 (my little 5 watt Blues tone monster), has just introduced the Harp Commander IV, a nice piece of gear by a guy who knows harp gear. Details can be found here.
The Harp Commander is a high-end piece of gear for sure. It’s clearly designed for both performing and recording, with a lot of gazintas and gazoutas (a/k/a inputs and outputs). You can feed multiple outputs at once, and you have different options for which signals go where.
The HC4 sells for multiples of what a Digitech RP sells for; it’s boutique gear with a price tag to match. We haven’t tested it, but if Ron built it, it’s built to last. Check it out.
