• Guys, we've spent considerable money converting the Les Paul Forum to this new XenForo platform, and we have ongoing monthly operating expenses. THE "DONATIONS" TAB IS NOW WORKING, AND WE WOULD APPRECIATE ANY DONATIONS YOU CAN MAKE TO KEEP THE LES PAUL FORUM GOING! Thank you!

I had heard and read so many times about how this is the ultimate reverb. I had tried Holy Grails and all else in attempts to add reverb to my non reverb amps, especially my 1938 Wabash. The Grail was nice but noisy and not quite as full. The other solid states were sometimes sirprisingly good but not ever really great.

All they say about the 6G15 Reissue is true. It is full and lush as you want it to be. Even with the verb level and dwell run lower it is still so much more full and resonant. The wife says it is a more "luxurious or expensive sound.

I have wanted one of these for quite a while and never could find a store that stocked one.

This is a keeper. Even with the stock tubes and PCB it is still miles ahead of anything else you can find. Someday I may do the hand wiring thing to it but no hurry.

Congrats, I love outboard Fender Reverbs. To make yours sound even better, replace the 6V6 with a 6K6. That's what the originals had. It's a tube no longer made so not really practical for a production piece of gear. However, they are not that rare and not that expensive and they do make a difference.

That along with an NOS perhaps RCA 12AX7 and 12AT7 will surely be my first and perhaps only mods to this unit. I have heard the 6K6 does make a big difference.

Thanks

Damn, you're right! An RCA 6K6. I always assumed it was a 6V6, as they look just the same.

Since I'm using mine as an overdrive, maybe I should try a 6V6....

Songsmith, swapping the tubes out really does make a great difference but to complete it, you can also change the 250pf(C10) cap on the circuit board to 1Kv 390pf, 470pf or 500pf to open up the sound a bit more. It make's it less brittle sounding and will increase the amount of low end response you'll hear from your amp.

In my rev unit, I installed a 1Kv 500pf....it sounds great....easy to do too if you can solder....the most time consuming part is getting the circuit board pulled out enough to do the mod....took maybe 15 mins total until I was playing through the unit again.

After the circuit board is pulled out a bit to work on it, simply locate capacitor C10 underneath the mix pot on the circuit board. (It's obvious when you look for it as it will say C10). Change this cap to a 1Kv 390pf, 470pf or 500pf capacitor.....pretty sure you'll be pleased with the results.

If you want to do it let me know at 1fatcat@adelphia.net and I will drop a 500pf cap in the mail to you. I won some on ebay and have extras....I thought the auction was for just one 500pf....but it was for 10 of them!

Fatcat is steering you in the right direction.
I did the mod on my unit a few years ago.
It was pretty easy,and made a difference.
There is a website with pics and instructions for doing the mod.I'll see if I can find it again and post a link.
