I have had a HRD for years and really enjoyed it when I was in my first band. I generally used it as a pedal platform and upgraded a few things (tubes, got an ext cab, and swapped the speaker for a WGS ET-65). It started having issues years ago that all aligned with the well known problems these amps have:

Good tone, but could be better

Unusable volume pot

EQ stack that can only suit one channel at a time

Reliability problems due to some component over-frugality and poor design by Fender

High noise floor

To solve all of the reliability issues I took it to an amp repair shop with a good reputation. I was hoping to have them perform the upgrades that Lyle (Psionic) makes so clear. They kept it for nearly a year, insisted there was nothing wrong with it, refused to entertain the notion of modifying it and returned it to me for an hour bench fee. Boo.

Well, I next considered installing the Fromel mod kit myself. Upon researching it I found out they’re in my area and can install the mods themselves for a couple hundred bucks extra. Thank goodness I realized that. I definitely would have botched that job. Amp work is way over my skill level.

The gentleman there are very nice and it was a pleasure to meet them and get my amp worked on by such knowledgeable pros.

I opted to upgrade the output transformer while it was on the bench.

After several days with it I couldn’t be happier.

The clean channel has a less woofy tone, like a Deluxe Reverb but louder (if desired). The volume knob is usable throughout the sweep.

The Drive channel mods are mind blowing. First of all, the EQ stack can be set so that both channels sound great. The gain can take it from light breakup to classic rock glory. The More Drive switch gives it just a bit more juice, vs the unusable boost it provides in stock form.

The best part…it’s dead quiet. You can dime it on either channel and it barely has any background noise.

I highly recommend Fromel mods, especially if you’re near Seattle and can have Fromel do the installation.

Glad it worked for you!

Good advice having someone who specializes in this do the mod. The Fender Hot Rod series have thin traces on their PCBs, which are very easy to lift and mess up. Overall, great value amps.

I have also performed the Fromel mods about 14 years ago on my HRD circa 1996. I also replaced both transformers and the speaker. This is the best sounding amp I have out of the six that I own. I will never let it go.

I should have modded mine back in the day. It was my first modern day tube amp. I like it at first but eventually, I fell out of love with it. All in all, for some reason Fender amps have never been my preference. The one I like the best and wish I had kept was an Excelsior. I out NOS RCAs in it, a 15" Blue Alnico Weber and modded the dark bright switch into a tone pot. That amp was amazing. I have had a Princeton, HRD, Bassman, and a Junior but none of them did it for me. Mods would have probably made me like them more.
