That Pedal Show | 7 months ago
Take the same guitar amp, same speakers, same cabinet: does the sound change when you wire for 4, 8 and 16-ohm output impedance?
Life too short for long YouTube videos? Please see the ‘Interesting bits and go-to sections’ information below.
Welcome to the show. It’s a super tweaky one this week. We spend most of our time on That Pedal Show talking about the Big Things that affect tone – different guitars, amps and pedals as you would expect, plus all the various things within those categories, for example pickups, components, wattage, gain, EQ, speakers etc etc etc. Well here we’re getting a little more nuanced.
You might think that your amp’s output impedance is one of those things that makes no difference – you just plug in the cab and play, right? If it’s a combo, it’s probably always just plugged in and you’ve never given it a second thought. As we discover in this video, the differences are there. Do you care?
Enjoy the show!
SAFETY WARNING: When dealing with amplifier output impedance and speaker matching, IT IS VITAL that you follow the manufacturer’s guidelines. Failing to do so could risk voiding your warranty and/or causing damage to your amp.
