#075

[TimS]

I've seen some intriguing descriptions of this amp on this site and was wondering how much is known about it circuitwise. Is there a schematic available, or if not, could someone please compare it to one that is?



In case anyone is interested, here's what I read about it:

"Steve Farris used #075 (built in 79/80, first one with ratio-control, presence control and "trigger" trim pot) on a lot of his recordings...wonderful glassy "singing" highs, that sometimes sound like bottleneck, even without bottle.)."

"Still very natural sounding and very glassy in the highs (depending on customer and eq settings). Wunderfull clear clean sounds. Clear and smooth singing overdrive with still a lot of highs but witout any harshness or fuzz"

"Some ODS I know of (e. g. #075) you can adjust in a way that (me at least) hardly hear any distortion "noise" that is in any way "seperated" from the tone. If you adjust an ODS this way, the rich harmonics, produces by the clipping of the OD-tube, are pereceived as a natural part of the instruments intrinsic tone."

Could you please cite the source and author of this - where did you read it and who wrote it?

Hi Zippy,

the one who posted these lines is me. So if you have any questions concerning the Steve Farris amp (#075), just ask and I will try to answer.

Hi TimS,

You will find some pics and infos on Rob Livesey's site (look for the series "# 075" and the pics of #75 in one of the Dumble "catalogues" that you find there).

After Steve Farris got #075 its circuit was constantly updated by Mr. Dumble. As HAD once told Steve Farris was one of his main inspirations for the ODS sounds

As far as I know #075 has a 250K T, 100K M, 250K B tonestack like most of the of the early eighties ODS, that have not been modified to the Skyliner tonestack in the late eighties. It is a (for my ears) very tastefull mixture of sound elements of the silver face toggle-switch ODS generation and the first blackface ones.

#075 and some of the early ODS like #002, 004 and 008 are my all-time-favorites in regard of the ODS-sounds.

I you have more questions concerning #075, just ask, and I will try my best to answer.

Cheers,

Max

Do you know if this amp had snubber caps on V2?
or when these caps were introduced, I'm running mine without them and prefer the grain in the od sound, but horses for courses....
just trying to figure if I'm chasing the earlier sound.

Hi Nick,

as far as I remeber it has the snubbers, but they have been tuned (like every detail in this amp) to the taste of Steve Farris (very tastefull in my ears) in a way that you still have a very "natural" and open OD sound with a lot of high-end blossom, that is only a tiny bit more "polished" and "compact" as the very early ones (e. g. #004 or #008). This amp has a lot of sparkle. If you listen to the solowork on some of the takes of Mr. Misters longplayer "Welcome To The Real World", and you try to hear through all the effects, you can perhaps get an idea of what I am talking about.

BTW: A very smart functional feature of this amp is, that the FX-loop is footswitchable (on/off). So you can use the Dumblelator (with or without effects) as a footswitchable option.

All he best

Max
