Is anyone aware of an enhanced reverb mod worth doing here or if that's what I really want should I just spring for a reverb tank like the '63 Fender RI or Kendrick models? Uh- for you techs, "spring" wasn't a pun- but I'll take it | ||

Anyone want to give this question (above) a shot? Or is the general concensus that the reverb is just fine? My amp is truly in primo condition-so please, if you're a good tech or possibly an EE, any thoughts? One guy listened to it and said- nah, that's just transistor technology-- you're asking too much of it--you're accustomed to tube pre-amp reverb. Well- perhaps there's a continuum here that no one's willing or able to talk about...(it's analgous to the same approach I generally take re; digital distortion vs. vastly superior -musically-to-the-ear analog distortion). Anyway- reverb improvement; I'd have the modification done if I can find a thoughtful, qualified opinion to provide direction out there need advice! Anyone? Thanks guys. Marc | ||

Hint taken... I can almost hear "whaddaya want now, MEAT in yer soup"?:-). Sounds like a gear/plastic call beckons:-(. | ||

Sorry about the apparent inattention.... 1. I have been really busy and have not had much time to devote to the site in recent weeks. 2. This IS a "prototype" message system that will become the full-time replacement of the current one as soon as I can swing it. Until that time, it is not directly accessible from a "button" on the site so fewer people know of it or have saved a link to it. 3. I personally have little experience with reverb circuit improvements so I can't really add much outside the ordinary "put a tube in there" response. However, thanks for using this system! You might get some more thoughtful responses when it becomes easier to find! Steve | ||

Hi Mark. Is your reverb weak or distant thus needing repair or do you just want more reverb? I repaired a MM amp with weak reverb and the problem was a bad cap in the reverb circuit. What a difference it made! I have been working on a lot of reverb stuff lately, perhaps I can help. TTFN, Dick Billups | ||

If there is nothing wrong with your reverb circuit and you just want to add a little extra sparkle to your reverb, solder a 0.1 microfarad gumdrop-style cap from the wiper of the reverb level pot to c34 where it joins the reverb pot. If you want to get fancy, add a switch for the cap that adds or removes it. Please let me know what you think of this mod... Cheers! | ||

I have never actually tried this, so I cant really verify the results, but..... The reverb tank could be exchanged for a longer decay. as I recall the tank they put in there was a medium decay tank, so you could order a long decay tank from accutronics, just make sure the input and output impedances are the same. I had a customer mention that he was unhappy with his reverb, on his HD130 and that was the answer I came up with. | ||

I haven't tried this because I think my 100rd has enough reverb but couldn't a guy replace the pot with one of a differnt value ,like i mean i think mine has a 25 k in it wouldn't changing that to a 10 or 5 or even a 100 ,250, 500k ..ect change the tone and how the reverb reacts ? |
