My first tube amp I bought was the Fender Hot Rod Deluxe III. I got it because thats what everyone I knew used and its what I borrowed for a long time to play on Sunday's. I bought it new for a great deal and used it every week for a couple years until I started wanting more from my amp. I was over lifting and carrying the ~50 pound amp several times a week to/from rehearsal and church and wanted a less sterile clean tone. I ended up picking up a new AC10 and couldn't be happier. Its got the exact clean tone I love, edge of breakup with some dynamics and it weighs under 30 pounds and is loud enough for rehearsals and is always Mic'd for actual performances. This has left the HRDIII collecting dust for over a year I'd say. Recently I've started recording and getting into running both amps together which creates a really cool massive sound. Furthermore I've gotten into setting the two amps as a wet/dry rig and those sounds have really floored me. The problem is that the HRDIII is extremely loud and way to big/heavy to load with the AC10 in my truck for live stuff so its relegated to collecting dust or being used sparingly on some recordings. My thought is that I would greatly benefit from having a second small amp to pair with the AC10 and could potentially bring both to play live if I wanted leading me to here. I have thought about selling the amp but the market for HRDIII's is pathetic, they go for dirt cheap used... ~$400 mark on craigslist. For $400 I can't really buy much to replace it so I thought about just doing a trade and posted an ad on craigslist. One day goes by and I've got an offer to trade straight across for a Blues Jr III with this massive list of mods (+ a mod reverb tank apparently). He told me he wanted to work on a deluxe to modify / learn how to make it better for customers. I know nothing about what any of the above means but apparently most of it falls under Billm mod territory and the rest is just to give it more reliable components. Stock speaker. Anyways I'm not sure how to value any of this, but the guy knows what he's talking about and builds/mods amps/pedals and talked on the phone with me for an hour about all of the above. I don't necessarily care about straight across equal value I just want to know if this makes the amp more or less valuable and if you with experience with the modded BJ or both the HRDIII/BJ can give me some insight on the differences/ how the amp behaves and whether you think it'd be a good fit. Basically I'm looking for a clean reverb/delay/pedal platform to pair with a vox AC10 running fairly hot. Back when I was searching for a new amp I compared the BJ and AC10 and much preferred the AC10 but as a complimentary amp Im thinking I might love it, and with the mods surely it should sound better...right? Am I crazy?
