He ' s the guy that CBS picked to tighten up the Fender amplifier product line they didn ' t tell him they were selling the company ! . I ' ve owned mine since 1982 , and have done a fair bit of research to figure out why my VERY heavy solidstate amp constantly refuses to suck . IMHO , your Dad ' s handed you an excellent amp . Everything these good folks have said is spoton . Here ' s what I ' ll addThe parametric EQ is a good friend , but there are so many ways to use it , you probably should take a notebook with you . Once you get a sound dialed in , tape the knobs with blue painter ' s tape so it doesn ' t rip the aluminum caps off before they get jiggled . Little changes make big differences on the EQ , and you can use the parametric to bump up or knock down a frequency just where you need it flattening out a resonant room . The part I like best is that it ' s perfectly continuous , unlike the slider EQ pedals . The reason the amp ' s so heavy is because the transformer is ' oversized ' for the design , and the case is longer fronttoback more wood creates a longer path , which improves bass response of an open cabinet . This was one of the earliest channelswitching amps , giving you separate clean dirty channels onthego . BTW it ' s not just you few people like the overdrive on channel # 2 . If the potentiometers get scratchy or ' gummy ', deoxit spray has been all that ' s needed . I ' ve only had to do it twice in 30 years . Robben Ford used one in his back line for years . It ' s much less vulnerable to getting jostled around than my tube amp . Plug it into a different cabinet my AHA ! moment was a Marshall 1960 B 4 x 12 and you might be very pleasantly surprised . I found many recommendations to swap out the stock Yamaha 12 8 ohm 50 W speaker I went with the Weber 12 F 150 B my other choice was the Eminence Patriot Cannabis Rex . YMMV , season to taste . Without changing out the speaker , you may think your pedals are dropping all the high harmonics . For me , it was like I ' d finally stopped playing with the cover on . google string yamaha g 50 OR g 100 ii 112 OR 212 ~ amplifier ~ artists OR ~ players OR jazz OR ~ musiciansrepair manualYamahag 50112 iiimanualsupporting linksSC 3 ej 1 owciAQhbNMU 7 GzTcampsgizmos 8551 sleeperyamahag 100 yamahag 50 amps . htmlampsgizmos 37431 dtelsleeperyamahag 100 yamahag 50 ampsg 50112 g 100112115210212 smpdfampsgizmos 37430 dtelsleeperyamahag 100 yamahag 50 ampsyamahag 100115 servicemanualpdf
