Let us know your findings.

Couldn't locate a '68 Deluxe Custom today but I did find a Princeton. It had literally 10 times the reverb of my deluxe. I could get tons of surf drip at 5-6 on the dial. I'm sure the princeton and deluxe reverb isn't identical but there's no way the deluxe has on 10 what the princeton has on 3. I don't even think it's the amount that's the issue anymore. After playing the princeton, it almost sounds like my reverb is there but far off in another room or something. Bad wiring perhaps? After all that discussion, I'm gonna do what some of you suggested initially and take it in to be serviced. Should've done that in the first place but at least I learned a bit in the process!

The PR's reverb circuit is similar to and operates as the DR (and the various re-issues and derivatives). I think something is definitely amiss within your amp and you're wise to let the techs at an authorized service center take a look at it.

The only thing that threw me is that the deluxe shares the reverb on two channels but I finally did find another deluxe '68 to try so now I'm 100 percent sure something is wrong. The reason I hesistated to take it in is because I don't trust the employees at my local guitar store. That sounds ridiculous probably but I was at a different location of the same chain today explaining my problem as a reason to try their deluxe and the guy wouldn't accept that tubes would be a cause for reverb problems because "tubes power the amp, not the reverb" but I'm assuming an amp tech does their repairs, not a sales rep lol.

Ha! Just don't get it. If I worked at a music store, I'd research every amp that came in to avoid looking like a knob. This guy doesn't even acknowledge the existence of pre-solid state technology.

Ha!

He was so sure of himself and got angry when I tried to tell him the contrary without being patronizing at all!

I'll update when I take the amp in for servicing on Monday and hopefully my local store is a little more Mcknowledgeable because I really like this amp otherwise. I always thought I liked the super bright blackface sound, but the bassman channel works so well for what I play. Having both in one amp is amazing.

I have both a '65 DRRI and a VM '68 Custom DR. The reverb on the '65 is so incredibly deep at 10 you could drown in it. At that level it isn't really all that useful and it feedbacks if the tank is in the amp. At around 5 or 6 the reverb is sweet and sounds great and doesn't feedback. The reverb on the '68 sounds even better than the '65's but is noticeably weaker - at 10 it is about as deep as the '65 at 5 or 6 which sounds great and is completely useful. I was thinking the the '68 design might have pulled back the highest reverb level to avoid endless complaints about the reverb feeding back - of course now they probably get endless complaints about the reverb being too weak :wink:

I had the exact same experience with my DRRI, putting the reverb past 7 was actually hilarious. Mine would self oscillate and amplify my buzzy bridge (another issue) louder then the actual notes. I did notice on the deluxe I tried yesterday that same thing, on 10 it was still really deep but completely useable. The goober helping me wouldn't let me touch the amp so I couldn't get enough volume, but the Princeton's reverb far outshone the DRRI's. My 68 deluxe however is weaker to the point that it's useless. This is why I was unsure if I even had a problem in the first place though, but if you can't get a drippy surf reverb on a 60's style fender amp then clearly something is wrong! They must of adjusted the reverb level to be useable on our planet's atmosphere and not having much up to 3 is normal, but at 5 there should still be a fair amount.

" The goober helping me wouldn't let me touch the amp so I couldn't get enough volume. "

Why did he not let you work the volume? Afraid you may scare the patrons? Too bad you can't find another guitar shop. Not too sure about this place you describe.

Did you try another Custom Deluxe Reverb amp, at this store?

Anyhow, I'd imagine that the '68 Custom Deluxe Reverb's reverb circuitry is similar, if not exactly the same, as the DRRI. So, basic voltage tests and wiring layout (including solder points) may need to be reviewed to see what the issue is.

Do you have access to a schematic of this amp?

Luckily the goober who wouldn't let me touch the amp was at another location where I went just to try another '68 deluxe. The location near me where I bought the amp just gives you a cord, tells you to pick out any guitar and go nuts! They don't seem very technically knowledgeable either but at least let you do what you wish while you're there. When I tried the goober deluxe, there was a very noticeable difference even with the volume so low.

I've seen schematics online, but voltage tests even are beyond my expertise unfortunately. I don't know how to drain caps so I don't electrocute myself and it might be a fun learning experience but I feel like that's not something I should poke around with and I don't have the proper equipment.

AFAIK, the custom board is identical to the DRRI board and even says DRRI on it. There'd just be the added tone stack and then a wire going across the inputs for reverb and tremolo on both channels like the Fritz mod on DRRI's. Maybe thats the issue, a bad solder or some worker / robot didn't do something at the factory? Figure I'll let them figure it out and at worst they'll just have to replace it and I'll have to wait a few weeks.

Could you post a link to the '68 CDR schematic? Let's review the stock circuitry, before doing any mods.

Thanks!

It's a brand new amp.

With a warranty.

And any mods or tampering performed by an unauthorized tech effectively flushes that warranty down the terlet.

I'd think twice before altering anything.
