[dominique@france]

Hello
YOU WILL FIND BELOW MY CONFIG TO GET CLOSE TO THE SOUND OF C SANTANA FROM THE 1980'S

preamp tube's
V1: 6062A / 12AY7 EH
V2: 5751 JJ Gold
V3: 5751 Tungsol

Power tubes:
V6 - V7 - V8 - V9 : MESA STR 440 GREEN MATCHED

TRIODE / SIMUL CLASS / HARMONIC

I'm getting close to the sound of Carlos Santana from the 80's (warmth and sweetness) but I'm missing a hint of nasal grain in the overdrive while having clarity...
What should I change in this set to get the sound I want?

RH2: GAIN 8 - TREBLE 8 - BASS 0 - MIDDLE 7 - PRESENCE CTL 4 (PULL) - MASTER 5
