Just want to offer some encouragement to those considering working on their own amp (and the like). The whole learning process was a welcome refuge during these uncertain times and I absolutely couldn’t have done it without many talented and generous techs on YT, Lyle especially. 🙏 Very much appreciate his courteous service. Plus, my outstanding luck with that same-day ‘65 OT has me thinking 2022 might not be so bad! Cheers to a New Year!🥂
Congrats on getting this gem back into playing condition. I also have taken the opportunity in 2021 to finally delve into basic amp servicing (changing electrolytics and resistors). So far I have done my 1969 Super Reverb, 1968 Bassman and 1977 Deluxe Reverb. Next up will be my 1978 Super Twin Reverb, but that has some wiring issues due to work a "tech" did about 25 years ago. He supposedly put in a voltage divider, making it switchable between 25/100 watts, took out 2 power tubes, removing some of the wiring. That will be a challenge to get back to original condition. I find Lyle and Uncle Doug's videos to be the most helpful in understanding theory and practical tech tips.
Hey all! This is Ian (the owner of this amp). Forgive my shitty play test. Lol. Minor correction for anyone curious about the cab and speakers. Cab is a Deluxe Reverb style cab (open back) with a 2x10 baffle from Guitar Cabinets Direct. Speakers are a C10Q and P10R combination. P10R was mic’d with the SM57 in the video. Lyle is the man! Send him your amp!
Hey Ian, I hope you enjoy your Bandmaster for many, many years. I bought a '67 Deluxe Reverb (very similar Ab763 circuit) and its just the amp love of my life. :)
Ian is a smart guy since he talked you into working on his amp. He is also lucky, ... a great combination. And thanks Lyle, this video set was a great masterclass on general amp inspection and diagnosis.
I just took receipt of what I think is a 1967 Bandmaster (have not had time to unbox the beast) to go along with my 1962 Bandmaster, which sounds AMAZING! This '65 sounds wonderful. Can you whisper, "QUIET"!?
Have a 65 bandmaster that had the screen resistors burn up. Replaced with newer higher wattage rated ones. Seems to work now. Owner claimed that after an hour or so of playing amp cuts out. Any direction you could offer on that would be awesome. Seems like maybe heat related stress. I should look at the tail resister like on the first video but thought I would ask. Keep up good fight❤
Yeah,, frustating that I was having trouble with google and youtube! I resubscribed and am thankfull for your content. Happy New Year but it's still pretty grim.
I did this sane mod a number of years ago, and the soeajers have a similar cone to the C8R. I find the sweet spot really narrow in the head cab as the lows get overwhelming / boomy but in a low mid way, very fast. Doing some circuit mods would help for me, are there any circuit mids on yours? What pedal are you using in the demo.
Back in the day these old Fender amps where the state of the art. Every working band, doing shows every night, these were the amps that did the job. Then the Marshalls came on strong. But all the local guys were blowing up the Marshalls. Did not last for a month before they failed. The old Fenders still sound great.
Nominally 40W. Usually more like 35W with the old Schumacher iron. One of the reasons BM OTs are prone to failure. Blow a speaker or have the plug disconnect from the external cab = no load = stress.
Unless you are old school, the vintage amps are not what you want. Some of the new stuff is amazing. Depends on how you want your guitar playing to sound. Easy for me, I build acoustic guitars. I also play electric. I know the sound I want to get. I want the guitar to sound like a guitar, not a kazoo. Some amps and pedals take the guitar into another dimension. Different strokes, all good.
