Really nice job, great work, that’s come out looking like new and I like the badge , back in the day I had a few HH cabs, mine were really reliable but pretty heavy compared to some now, this was one I had
Once I’ve learned a song and played it quite a few times I tend to drift away from it and only play it once every now and again, one Bassline I never tire of playing is this by Robbie Shakespeare, it really drives the song
I don’t know much about pedals but playing reggae and dub I did experiment a bit with a few to get really deep bass , the only one I found good that I still use occasionally is the Ampeg bass preamp, you can boost the bass and it still sounds good without that distorted sound if your cabs can take it, there might be a few suggestions here
I don’t know that song, but if I need to up my speed for certain tracks I do pretty much what Acebass does above, I’m not a very fast player so I break it down into sections until I’ve got all the notes comfortably and then slowly up my speed, I did include some speed exercises into my practice routine before and it definitely helped, good luck ☝️
Would the stamps on the pots give you any more information , you already know the year , but when you put all your findings together it’s all good to know
I’ve always got a bass within reaching distance, I play it unplugged just to work out basslines or noodling , I’ve also got a Yamaha SessionCake for headphones which is quite a handy little thing
