does anybody know anything about onboard preamps for guitar that can give me boost or cut of MIDS????
for mid boost, you could try the Eric Clapton mid boost preamp...
Small EQ and distortion changes in early stages can have large influences on later stages.
Tune the Booster to the Chain, this includes Guitar, effects, amp.
Depending on the circuit and the transistor used, many different boost tones are available
I use:
Fetzer Valve Jfet
Stratoblaster Jfet
Mini-booster Jfet
Mosfet Boost
Dual Clean Mosfet Booster
Rangemaster Ge PNP
Vox reble Booster Ge PNP
Brian May Treble Booster Si NPN
Micro Amp JRC 4558
???????????? All have at least one sockketed cap and transistor.
J201 Smooth can be clean-ish / high end sparkle
Mosfet Big CLean Loud
Ge transistors impart tonal characteristics including EQ and Distortion, probly a bit 'bias finicky' for onboard guitar use
...Current consumption?...
...Bypass?..
For mids cut: Notch Filter or Tone Control...[ ]
For mids boost: Smaller input cap or cap in signal path cuts bass [LP filter], cap from signal path to ground [HP filter], cuts highs..tune for desired midrange boost response
Quote from: petemooreSmaller input cap or cap in signal path cuts bass [LP filter], cap from signal path to ground [HP filter], cuts highs
Wouldn't the filter flavors be named the other way 'round?
Cap in signal path cuts bass (HP filter)
Cap to ground cuts highs (LP filter)
Maybe I'm all mixed up.....just trying to understand high and low pass....
High pass cuts lows, low pass cuts highs, right?
Nope you got it right...typo sorry
anyway ''socket' when in doubt... :oops: 8) Dohh...lotta help I am sometimes...
I'm curious what this Musitech (http://www.stewmac.com/shop/Electronics,_pickups/Preamps:_For_magnetic_pickups/Musitech_Preamps.html) preamp circuit is...gotta love that shrink wrap job. :wink: For $80 I won't be buying one to trace anytime soon, though it's gotta be a good circuit for StewMac to carry it.
