MOSFET (solid-state) power amps are designed to supply as clean a signal as possible... with the lowest signal-to-noise ratio.... and the lowest Total Harmonic Distortion (THD)... so they are used primarily for Public Address (PA) systems for mixing boards, for amplifying vocals (through a microphone), keyboards and bass instruments which need clean volume.rjfoster said:So how is the SOUND of a MOSFET amp compared to say a good old fashioned Marshall tube amp?
I fully agree... especially about Ed using his Marshall head as an entire preamp and the MOSFET H&H's as true clean "power amps". And it's absolutely correct that his tone would have changed if Ed had used a tube power amp which would have directly altered his overall tone... perhaps in a good way or even bad... we'll never know. :dunno:VHfanOU812 said:It all depends on where you get your tone, and harmonics. In my post above with the link to Ed's set-up...he turns a head into a preamp and get's the exact sound he wants...then powers it though a MOSfet amp. If he used a tube power amp (which he could no doubt afford) it would screw up his sound. They have their place if you know what you are doing.
