An amp caught my eye… Supro content

[Bach5G]

I was just heading out the door of my LMS, having picked up my bass trombone from the the repairman, when a Supro Keeley Custom 10 caught my eye. Size and weight of a Princeton but rated at 25 watts. No chance to play it.

This is what Supro says:
“Designed in collaboration with Robert Keeley of Keeley Electronics, the Keeley Custom 10 is built to seamlessly integrate your pedals into the heart of an all-tube Supro amplifier. The preamp and 2-band EQ section are voiced perfectly for running your gain pedals in front of the amp, while still maintaining Supro’s signature midrange heft and phenomenal touch dynamics. Meanwhile, a transparent effects loop provides the ideal point to inject your delay and reverb effects into the amplifier’s all-tube signal path, avoiding unwanted distortion on modulation effects. A master volume circuit allows you to control the sound pressure level coming from the speaker, while pouring on copious amounts of gain from the ECC83S-based tube preamp or your favorite dirt pedals. The Keeley Custom 10 offers 25 watts of Class A power in a convenient 1x10 format, featuring our custom CR10 speaker.”


And so on.

I don’t use pedals but if the design is for clean, lots of headroom, wouldn’t that work for most jazz?

Has anyone tried one of these?

I only know Supro was Led Zeppelin’s “secret weapon”. That was about the right overdrive. And there is a DIY Supreaux stomp box that imitates the sound.

Wampler, JHS, Keely have all had ‘pedal platform’ amps made for them in recent times. I can’t see why not good for Jazz, but never see them on this Gondwanan continent…..

It all sounds like marketing waffle to me. Pedals are designed to be attached to amplifiers. Why would a special amplifier designed for pedals be necessary?

Zealandia is about half the size of Australia, but only seven percent of it is above sea level.

Supros (the new ones) do have a particular tone (unlike Fender), and I think they can be very good for jazzier tones. I have a Supro Tremoverb and it's my favorite for jazzy tones with my Gretsch. And I also own a Princeton Reverb, which I prefer with other guitars.

Think of the Supro (clean) tone as, when compared to the gold standard Fender Princeton/Deluxe blackface:
-Supro has more low end, rounder high end, and alot more mids. IMO closer to Fender tweed.

I don't know about the sound, but it sure is a very cool looker. Love the light blue covering.

I only tried Supro something with a trem and verb and thought that it was pretty good, not a Fender but still a decent clean sound that was a bit smoother, should work great for jazz..

If only they provided 9V and a good deck on the top to put the pedals (ok maybe not the wah wah)….

I owned one of the originals on which this amp is modeled, a 1961-62 1624RT. It had 6973 hifi tubes, rare in guitar amps but common in jukeboxes of that era.

The transformer was not Fender weight; the cab was flimsier though not as flimsy as Magnatone; the 1624 would not have stood up to a Princeton, however its wattage was rated. It was great for a certain breakup, blues, rock, but in a band I had a Mesa V-Twin in front of it in order to compete with a drummer and to solo. Great 12” speaker. I sold it when it was worth way more than I paid.

This modern version—isn’t its PR aimed at anyone but a jazz player who doesn’t use pedals? But that’s the point of an effects loop in a modern amp, to connect effects. My impression is that the revivified Supros (and Magnatones, which I have auditioned) are more solidly built than their forebears, but have lost some of the tonal idiosyncrasies in their unobtainium power tubes.

If it’s affordable, and the transformer is beefed up since 1961, and the 10” speaker is good and the tubes aren’t rare, it ought to be okay for solo/small combo. Especially if one doesn’t want EQ decision paralysis (ha ha, I have a Henriksen for that).

My (modern) Tremoverb takes 6973s... there are current production versions of this tube. Maybe not right now (with the whole "tube scarcity" thing), but they are available.
