With so many PRRI threads it seems about time to kick off the PRRI Club Thread. The amp has been around long enough to have the membership by now.

Mine has tilt back legs added and an upgraded OT to improve bass response.

How's yours? Do you love it?

I'm in...I got mine in July '08 and I really enjoy the amp. I've used it for a couple of small gigs and practices but mostly just strumming and twangin' at home. I've done the following work/upgrades on it.
1. Added a piece of 1" aluminum angel to stiffen the baffle. This was quick and easy and took care of the baffle rattle.
2. Hardwired the cord...I didn't like the IEC socket/removable cord. This is nice because now I can put the cover on without having to remove the cord...and I can't loose it :)
3. Added 14" tiltback legs...a no-brainer!

Count me in.

Got mine in 2009. Billm fixed the rattle (actually mine was documented on his website) and replaced the 6V6 output tubes with JJs biased at 23, and upgraded the OT with the ballsy TO2O. The amp is outstanding now. I tried a Weber 10F150T speaker for a while, but put the stock Jensen back in, as the JJs and new OT fixed the farty bass, and the stock speaker delivers fantastic Fender cleans.

The TO20 OT worked like a magic bullet in taking out the fartiness on mine. With a bunch of guitars and amps I've found a few tasty combinations over time. The PRRI has such great drive at listenable levels that I'm enjoying a particularly sweet honeymoon.

Right now I'm getting delirious over that place with the amp dimed and the guitar volume rolled back to the point on my Esquire where it's the pick attack that crosses the clean/dirty line. With the guitar tone rolled back to "aggressively tame" it's a sound I could play all day.

Dadical... tell us more about the transformer upgrade. My concern was voiding the warranty. But if the change is significantly better, it sound like the right thing to do so...

- how much more clean headroom
- how much more volume
- how much more low end

Sounds like an easy change.

"- how much more clean headroom
- how much more volume
- how much more low end"

"How much" is a hard thing to say without having the amps side by side so you can hear it. What is easy to say is that you will definitely notice the improvement - instantly. You won't have to go tweaking around searching for it. The flubby bottom goes away, virtually completely. In fact, I did have to go tweaking and pushing around to try to get it to misbehave. It stayed clean, full and round all the way into overdrive.

As far as clean headroom, I'd say it's not that big a difference if you compare to having the bass turned down with the old OT. The amp still has the great, predictable overdrive, but it *seems* to have better headroom because the flubbiness is gone so the output is overall cleaner up to the OD levels.

How much low end is again a function of cleanliness. It is definitely more useable low end because it doesn't go all farty on you.

The PRRI has a strong low end component to its natural drive. It's got a real snarl and growl on the bottom when pushed. I wound up playing mine through several different speakers to make sure I had any speaker or baffle issues eliminated from the amp itself. Over the last day or so it's been run through a single G12T75, a pair of G12T75s, a V30 4X12, a RW&B 1X12, and a 4X10 bass cab. It definitely snarls and growls when pushed. The good part is that it grinds regardless of the speaker arrangement so it is the Princeton circuit you will hear. The OT completely cleans up the speaker issue.

After all the mention of overdrive, I think it's important to say that before reaching the drive levels, the amp still retains that beautiful Fender Blackface clean.

Lovin' mine to death!

No rattle problems and I'm keeping it stock except that, like Dadical, I added Fender tilt back legs (a MUST!).

Got mine last year and still discovering the tones this thing makes. I added a baffle stiffener across the top, stuck a Weber speaker in there, swapped in some better tubes, and I'm loving it. It sounds pretty huge for a small 10" combo. The bass tones are pretty thunderous.

I'm in...

Got mine last year. I guess I'm one of the few that doesn't have the buzzing problem. I've turned mine up, cranked it, even played a bass through it, and no rattle. I keep thinking I must be missing something, but I figure I would fix it if it comes.

Amazingly enough, mine in still stock. Amazing because, it's the only piece of equipment that is still completely stock. I'm the type of person that puts a screwdriver and a soldering iron to my brand new guitars after the first month.

I'll probably put a new OT and a set of JJ's in it as soon as I figure out how to measure the bias. But I'm not in too much of a hurry cuz I like way it sounds.

It's a keeper.

Mine never had the rattle, but after the chassis R&R I put it through some hard workouts to make sure. According to the experts the chassis position in the cabinet can contribute to a rattle issue and there is a little fudge room during installation.

I have not been able to hear a PRRI yet. I'm sure it has a great clean sound. I would like to hear about it's natural overdrive sound without using a pedal. At what volume does the PRRI start to overdrive and how does it sound? I used to have a DRRI. Does the PRRI's overdrive sound about the same as a DRRI's overdrive?

I've lost your post on the degree of difficulty to hardwire the power cord. Please restate!

6L6 - That was someone else's mod. I'm still using the modern plug in cord. Maybe if you find the post you could link it here?

That was me that modded the cord...It was pretty easy. I got grief from most of the guys because it probably "voids the warranty". I think it's an improvement and I have had no problems.

I posted a thread on it several months ago when I first did it but I can give you more details and a couple of pics if interested.

Figaro - The level where the PRRI OD comes in depends on the type of pickups and volume level of the guitar. Generally, if the guitar is turned all the way up, the OD will start somewhere between 4-6 on the amp volume depending on how hot the pickups are. Humbuckers start to overdrive sooner. Turning the guitar down will raise the level of the amp before OD begins.

To my ear the PRRI has a hotter or grittier overdrive as compared to a DRRI. I hear the DRRI as smoother.

Hope this helps.

Thanks Dadical, that's the information I was looking for. I'm glad to hear that the PRRI will overdrive sooner than the DRRI.

I've had mine for a year now. Unmodded, and I intend on keeping it that way. I had a minor buzz problem with a neck Tex Mex humbucker at volume once, but no longer have those pickups. I have not found the problem with any other pups as yet.

very sweet sounding and is a great compliment to my other amps.
