Pro's, con's and changes to the deep switch?

[Mark]

I'm thinking about putting a deep switch into a #0102 clone, the idea is for something a little different when the mood takes me. I've heard it delivers realistic jazz tones where the jazz/rock switch doesn't quite.

What are your thoughts, what have you tried?

Look forward to your reply.

Hey Mark,

My experience is pretty limited with the deep switch but here's my two cents. I never really cared for the clean tones I got from any builds I ever did with a classic tonestack (so I always ended up ripping them out). I think it needs the deep switch for the cleans to shine. One the other hand, builds with Skyline and BM stack have great cleans and the deep switch really adds nothing of use. The mid boost however, is a great asset for the Skyline - seems many players just can't get enough boosted mids, particularly in OD. So in a nutshell - classic TS with deep or skyline TS with mid work. (thus my limited experience with deep)

YMMV. I'm sure I've annoyed someone with this gross simplification.

I'm an oddball I think (I suppose it is a given at this point.)
I like a skyline TS with a deep switch engaged, Mid boost engaged and Deep engaged and sometimes bright too (though I never use ones as big as dumble did...to shrill for what I like). Bring the gain up a bit to make up for losses, bring the mids low.
Imho this is a great tone... much like a "better then BF" fender.
Obviously not a lot of amps have both a mid and deep switch... but you can do a deep on a DPDT pull pot...
If anyone has an amp with these features give this a try and let me know if I am crazy.
When I need "Garcia" tone from one of these amps this is where I go...

I rather like the deep switch if you are doing either a low plate Skyliner or a classic..That's just me

I tried the deep switch when I first built my ODS.
I didn't care for it and changed it to mid boost.

Thank you for the replies, I dare say the deep switch has quite a noticeable effect on the tone. I dare say I will put it in and see how it sounds.

Has anyone played around with the resistor values?

I imagine the 270K resistors are there to provide some isolation between the areas the signal comes from, while the 10K is there to tune the amount of depth.

I'd be inclined to think adjusting the value of the 270K resistors and 10K resistors would vary the effect of this circuit.

I'll report back my finding after I've duly experimented with the circuit.

[markusw]

To my understanding the 270k connected to the bass pot together with the 10n forms a low pass filter that is mixed with the "dry signal" at the volume pot wiper via the second 270k acting as a mixing resistor.

Decreasing the first 270k should shift the low pass to higher frequencies and thus add more mids (but also bass) to the deep switch. Decreasing the second 270k should increase the effect of the deep switch, thus adding more of the low pass filtered signal.
Increasing he 10k tail should change the slope of the low pass filter, like a treble pot on a guitar.

As I said "to my understanding"...I may be completely wrong

[Mark]

Thanks for your input, I'll give it a try and see what I like.

Mark, here´s my two (Euro) cents:
A couple of years ago I was recording with my 79 ODS on somebody else´s demo, and was asked for a more "Fender-y" tone. I activated both the "Deep" and "Bright" switches, without changing the tone controls, and everybody was happy. Personally I feel the "Deep " is very useful , even with the "Skyliner" eq, so I would definetely recommend it.

Have fun Marcos
