Dennis is AWESOME. He is very knowledgeable. I brought a vintage Randall RG100es to him that was having issues. Few days it was fixed good as new. He also fixed the footswitch, and had me bring my cab in so he could look it over. Price was more than fair, so I tipped him as well. He is the only person I trust with my amps and effects from now on. 10/10 from me.
