) to prevent "loading down" the guitar pickups, which would otherwise result in a dull, muffled tone. Tone Shaping & Gain:

This stage takes the low-current signal from the preamp and converts it into a high-current signal capable of moving a speaker. (6L6, EL34, 6V6) or power transistors (MOSFETs, BJTs) are the muscles of the amp. guitar amplifier electronics basic theory pdf

Provides the massive current needed to physically move the speaker cone. ) to prevent "loading down" the guitar pickups,

. The power amp uses high voltage and current to create a powerful replica of the preamp's signal Roland - Global Output Transformers 6V6) or power transistors (MOSFETs

Using larger tubes (6L6, EL34, 6V6) or high-power transistors, this section multiplies the current to drive the speaker. Key concepts here include:
