jeckyll & hyde curiousity...

[nightingale]

hello~
went to a show the other night, and a guy playing a  gibson 335->MXR micro amp-> jeckyll & hyde, through a 2x12 blues deville... and had some amazing overdrive tones! i'm not really looking for the schemmo, but i would like to know what "type" of circuit lives inside that box... has anyone ever looked inside one of those things? i beleive there are two switchable stages...
curious,

SOUNDS
Overdrive sounds from the Jekyll channel alone are instantly pleasing. There's a sonic depth and smooth chocolate-coated sustain that's reminiscent of the original TS808 Tube Screamer. The way that the pedal interacts with the amp and is sensitive to playing dynamics is sheer magic. If you've got a valve combo that needs a kick up the rear-end, this is the pedal to administer it. Even in the high gain Hyde mode you can summon 'break up' sounds from the Ultimate Overdrive with the gain control set low. This gives a slightly more ballsy sound which makes whatever you play seem raw and dirty. In fact it's a bigger sound altogether, similar to that of a closed back 4x12" cabinet with all the characteristic 'whoomph!'.

Hey Ryan,

Are you talking about The Strokes? (Nick Valensi)

[nightingale]

thanks ansil~
i might have to track down a retail place that has one and try it on... i guess thats why they call it "the ultimate overdrive"...

Hey Ryan,

Are you talking about The Strokes? (Nick Valensi)

i wish i saw the new strokes tour...no it wasn't nick valenci, but he does have pretty much the same setup... give or take a 90's epi riviera... this guys name was andy, and he plays with the "low flying owls" from cali, they are kinda black rebel motorcycle clubish... super good!

i have a blues deville 4x10, and have built lots of boosters, but i've never heard tones like those... i guess i need to check out another screamer type circuit, and mess with jack ormans mods...
best,

This will probably get me abused by the TS lovers but try the Marshall Blues Breaker 2. I bought a couple of weeks ago, and on a fender amp and reissue tele. it sounded way better than the tube screamers that they had in stock.

I havn't had a chance to trace the PCB yet. But they have changed the pedal quite a lot (they have added some clipping LEDS (well I assume for clipping) for since their original BB pedal.

It's also pretty cheap (as pedals go).

[Ansil]

you could mod a 808 to give you that type of tone.. or you could take a stock ts9 and build a little 386based tubescreamer and use them together.  the 386 sounds great as a tube screamer.

IIRC one side is a TS and the other looked like a marshall shreadmaster circuit.

[petemoore]

Where did you get the schematic for the 386 TS you like?
 Spose I could take A Look?

[Ansil]

its on my site in the drop down menus

i'm also interested in that lm386 ts. Sounds like a good project.

[Ansil]

it is.. it is amazing you can leave out the whole second opamp stage and just use a 1k pot instead of the 1k resistor for your eq controll

vary flexible and DAMN!!!  LOUD!!!!.. not to be underestimated.

i am in the process of slipping oneinto a ts9 pedal so i can prove a point to my buddy..

Or the old Marshall Bluesbreaker.  Almost exactly the same except for a few different cap values and some other tone control differences.

[nightingale]

wow~
i must have subconciously recognized the bluesbreaker tones in the jeckyll and hyde ... because i just added that to my build list today... very strange!.. and i gotta try out try out ansils 386 design... if i can figure it out..! DIP circuits give me trouble sometimes tho...
thanks for the good reply's,

Ansil's just 'dropped a 386 in the TS's OA position.
 All the connections are the same except the OA's...386's pinouts are different as well the 386 is a single OA so you would need two.
 Look at the OA's pinout...hook +to+ Gnd to Gnd etc output to output...the little design at the bottem of the TS schem is how a prodiddler would get a 386 properly connectid in a dual's socket?
 I plan to just work up a TS, but with the sockets wired for a couple 386's

actually i ddesinged two 386 type clones. and found a way to just drop a 386 in the same posisiton
