Ampeg Reverberocket 2

[Jazzman301]

So my 67 Reverberocket 2 GS 12R was just delivered yesterday so I thought I would do a quick review.

It has the following tubes:
2 x 7591
2 12AX7
1 6U10


I would say this is perfect for jazz. Its a bit of a one trick pony in that it will only really do cleans unless you crank the hell out of the volume. There is no gain dial. It seems to stay clean until you reach the crazy end of the dial.

The reverb, Ampeg calls this Echo, is very nice. Although if you crank the reverb up it seems to add a ton of treble and the highs get really accentuated. But at normal levels it sounds really nice and like a good spring reverb should. The tremolo, though not much of a tremolo guy, sounds as good as everyone says. It really is a nice deep tremolo.

The single jensen 12" speaker sounds nice and warm and round but can get "crystal" clear if you dial back the bass and up the treble.

Overall I would say this is a great amp and would work well for anyone playing clean tones from nice warm jazz(can easily dial in a darker Wes Montgomery or Jim Hall tone) to clean country chicken pickin. A great and versitile clean amp. I would not ever recomend this for distortion unless you heavy into pedals.

I will try to get a playing sample together sooner rather than later.

Hope this helps and thanks for all the information in the various other amp threads.

I had a Reverberocket 2 but it was destroyed in a hurricane. I've since replaced it with a 65 Gemini 1 which works extremely well with my D'Armond pickups. The Ampeg amps were oribinally made for jazz type music which is why it sounds so good. The big problem is the low availability of the 7591 tubes. If you can find them, they're really expensive. The solution is to find a really good amp tech and have him/her convert the 7591s to the 6L6 type of tubes. Will it change the sound? Probably but how noticeable will it be? At least if the 6L6s go out, the amp becomes a lot more fixable. Enjoy the amp. It's one of the greats.

I found a full tube set on ebay for about $85 shipped. Seems like a decent deal. I think the amp still has the original Ampeg tubes.

It does sound really good for jazz. I wonder how those 7591 tubes compare to the 6L6

I think the 7591 tubes may have been a little warmer in sound but I wouldn't bet on it. I think I read that the 6L6s may make the amp sound a little brighter. With some creative adjusting, I'm sure you could dial that brightness out.

EH make a reissue 7591A tube which I just saw listed for $39 a pair.
They fall in between the 6L6 and 6V6 in terms of output.

JJ, Sovtek, and Groove Tubes also make a 7591 as well as the previously mentioned Electro Harmonix tubes. I would stick with the 7591's they are an excellent sounding tube. Ampegs are great amps. Congrats.

I had no idea thay reissued those tubes. Do they make enough of them so they're not too difficult to find or are the reissues just as hard to get?

[Franz 1997]

They are even listed on Amazon.......although, yes, there won't be much of a demand for them. Cheap enough, though.

You can get them from most of the tube places like Antique Electronics Supply, Tube Depot, The Tube Store etc...
