Let’s Build an Amp
My dad’s gonna build a guitar amp
This is pretty cool. I’ve been playing guitars few a while now and have gotten pretty familiar with the ins ‘n outs of guitars; I have no problem taking ‘em apart, modifying them, putting them back together… and, I’ve even built a couple. However, through all these years I’ve remained blissfully ignorant to amplifier technology; I have no idea how they work, what the internal components do or anything like that… that’s my dad’s world.
My dad’s taken a petty decent interest in my gear. Whenever I get new stuff he’s always checking it out, has done dozens of electronics (pickups etc) mods for me & has taught me how to solder and do some of this stuff myself.
A couple weeks ago I was playing a bit and wasn’t too happy with any of my amps (I have 4 at home). They all left something to be desired. I figured I’d look for something new and started doing some research, checked out prices and read a ton of reviews. After a while I was pretty frustrated, pinged my dad and said “hey, dude, you wanna build me an amp?”. He lit up.
As far as I’m concerned my dad’s an electronics genius. He’s worked on all sorts of electronics for 40+ years & I’ve never heard of him not being able to mod or fix something that has wires. So, I’m pretty stoked.
Right after bringing up the idea my dad started flipping through schematics for various Marshall amps. A few days later he declared he needed a physical amp too. Due to their popularity we decided that we’d use a JCM800 as a reference. But, after reading up on some forums I decided to go with a late 70′s JMP 2204 w/ master volume instead. A couple hours of hunting later I found a sweet ’78 in pretty awesome condition & bought it.
Here’s dad w/ his new toy:

Oh, the irony: I just bought my dad a Marshall for him to take apart and dissect… 15 years ago when I asked for 1/2 stack his reaction was “um, no!”. LoL
This should be pretty sweet. Dad’s been going off and telling me all sorts of stuff he’s learned about Marshalls, expressed some discontent with some of their designs & is flat out stoked to take on this challenge. He’s already been sketching out some ideas & had the JMP opened up minutes after it arrived. LoL.
I’m sure we’ll have a working amp pretty soon. I’ve got a pretty good idea for where I want this project to go & am positive dad can make it happen. It’s gonna be pretty rad.
Rock ‘n Roll
