FDP Forum / Amp Mods, Repairs, and Projects / NAD 65 SRRI


United States

Nov 26th, 2016 02:40 PM   Edit   Profile  

So I purchased a used, very good condition SRRI and holy hell, what an amp! It is LOUD, percussive and all the things I read about the amp is essentially true. It really feels like a "live" amp, it cuts really well, and tends to have an "overwhelming" sound to it. Literally, like my ears want to run away lol. It's LOUD!

That said, I had purchased this amp to replace my 65 DRRI...and I found out a lesson I did not want to learn...They don't do the same thing!!! The DRRI has an acoustic quality and is smooth as silk, but conversely doesn't cut as well as I would like. The SRRI on the other hand just cuts for days, but isn't as sweet or silky.

So that's all anywyas, NAD! I'm really happy, and kind of surprised in that my expectations were met, but in a curve balled way. I really like the feeling of the SRRI and how I feel very interactive with the amp. Likewise, the feeling of the DRRI is very different, and really demands a jazzier and smoother style of playing (but can get dirty at higher volumes). So, bank be damned I suppose, if I can keep them both I'm a happy camper!

Hopefully you won't have to carry it around much.



Why do I keep fixing things that work?

Congrats on your new amp and they are really sweet!
To address some of your conversation about the DRRI, at almost every performance I've been to the guitar player had their amp elevated off the ground and enjoyed every sound emitted from that amp. They either used an amp stand or had it sitting on a small speaker cab/chair. I know this was done to get it more ear level, but that amp sounded so good with every guitar he plugged into it. My favorite was the ES335 with a Tube Screamer, with just a little grit when he dug into it. One of the best earthy tones that made me cry to hear it. I asked him what he had done to it and he told me that he put JJ tubes on all the power section and old GE tubes in the preamp section. It was simply glorious and that tone lives in my minds eye to this day!
That's all I wanted to share with you.
My dream amp is the Super Reverb but would settle for either a 59 Bassman RI or the 4X10 Hot Rod DeVille. A friend that I jam with has the 4X10 Bassman and likes for me to play rythym guitar through it. I'm hoping against hope that I will be able to acquire this amp from him someday! Our band has a New Year's Eve show to play and since he is coming, I get to use that amp. ....... talk about wetting your pants, my bandmates will be drooling over the tone this thing puts out! Simply, Strat-a-luscious! My Les Paul sounds excellent through it as does anything played through it, but a Strat with a little reverb and some grit, well, just make sure to wear a diaper! Lol

4-10s move a lot of air! Very punchy and expressive IMO. I've owned two SRs, a '67 and one I built from a Bandmaster Reverb. Loved them both but now have a one of my dream amps, a '61 brown Concert. Also a 4-10 configuration but with that luscious brown front end and tremolo.

Enjoy the SRRI. Have the bias checked. If it has never been done these are notorious for being biased cold from the factory. Check it out.

I've played through a SRRI a bunch. It sounds loud at first but on stage with a drummer and bass amp going it's exactly what you need to cut through the mix. That's why you see it as standard gear for a lot of touring pros. I think it's the only amp Derek Trucks has ever used.

...and yes it is heavy. You will be shopping for a handy foldable cart.

Cal-Woody: I agree the DRRI is a great amp, I would honestly keep it if I had the funds (and it wasn't so quirky). I personally prefer the tighter bass of the SRRI, as well the tremolo & reverb are more usable imo.

Hammond101: Thank you, and yeah I have to imagine the bias may be a bit cold, or the amp is just different than my DRRI, which gets LOUD after 4. The SRRI really doesn't get loud and distorted until about 8. I'm not sure if that's the bias or what, but it's definitely noticeable. That said the amp sounds really good and is quite, so for now I'm not going to mess with it.

Larryguitar19: I'm actually just a hobbyist, I just found that the DRRI did one thing, and that thing wasn't what I wanted. I wanted a tighter bass end, and an amp that projected without struggle. When I sit down I can play comfortably at low volumes. I'd still say the DRRI sounds sweeter, but the fact the SRRI is moving so much air makes it easier for me to play without feeling the needs to jack the volume up way high.

We gigged with one in the 80's for years. Since the guitar player didn't use the normal channel, we pulled V1, which kicks up the gain of the Vibrato channel a little.

Then we put the 12AX7 from V1 in the PI slot (the 12AT7 next to the power tubes, which gave a little bluesey, tweed-like quality when pushed.

If we played a loud, outdoor gig, we'd put the 12AT7 back in.

Works great with a DR too.

I tend to prefer the normal setup Steve, the tremolo & reverb tend to sound better with both v1 & v2 in place, at least that's what I found.
