The circuit is a versatile building block anyone can use. This book does not cover tube circuits or unique aspects of guitar amps but is V1a provides an input buffer and gain. In overdrive, V1b provides modest gain and a crunchy sound.
v1, v2, v3??? Preamp positions? Can somebody explain?
Figure 2 shows the tube-based guitar amplifier's schematic. I'm thinking of starting to experiment with different preamp tubes.

Before I Schematic from input to out labels v1b v1a and v2a. Another part of the circuit may use the other triode of that tube and will be indicated as V1b.

It's much easier to analyze an amp circuit by studying its schematic than looking at its layout diagram. V1A is one half of tube V1, V1B is the other half. The preamp tube V1 (Valve 1) is made up of two separate triodes called A and B.

After the Grid Stopper the signal hits Tube V1A's Control Grid, pin 2 in the schematic above (our 12AY7 preamp tube is actually two tubes in one--a twin triode--and V1A means 'Valve 1, first triode). V1A is called a triode because it has three electrodes (control grid, cathode and plate, a tube with a fourth, screen grid electrode is called a. Wiring Diagram for Pickup Models: Tone CircuitsTM 2 & 3-Band Active EQ Preamps for Bass STC-2A, STC-2P STC-3A, STC-3P The basic steps for installation include: Proper operation depends on proper hookup of all connections; observe color codes and wire locations carefully.

Most people just buy tubes and randomly stick them in. I'm sure the factory didn't give much thought to it either.

Here is the run down on the tubes. Remember, a 12AX7 has two triodes called A .Explanation of what a Gain Stage is? | Telecaster Guitar Forumpreamp tubes | schematron.org

You commit an error. I can defend the position.
Quite right! It seems to me it is very good idea. Completely with you I will agree.
