Sounds like you know some good stuff already; yes Washburn make great guitars, and to boot, the nut and pick ups are most affective of tone, and usually where cheapness is present in more accessible models. Ive changed both on several instruments; although nowhere is a nut more crucial than on an acoustic.
yeah dont take formal lessons, and if you can, this will be hard, if you want to make music of your own, try and copy your heroes as little as possible, as you only end up sounding like them in an unattractive way.
New guitar sounds a rightr menace; Ive been given a pointer on a few underappreciated metal machines, and was told, to keep a look out for a Kramer Pacer, brutal and well built but quite cheap. If you ever see one or like me, start to acquire a collection.
So Amps, Im into amps more than guitars I think. You do have to get good gear, because if it doesnt sound good you put it down, and lets face it, bleeding fingers is enough! There are some great 90s Peaveys around, before the 5150 and 6505, Ultras, which are cheaper but of astounding quality, I have one of these, and you should be able get into one for under £300. The Blackstar HT5 is marker leader, still 10 years on, for smaller home amps. The only solid state amp of enough quality is the Roland JC40 or 120, but they are really not fashioned for metal. Then again a Peavey Bandit is solid state and I know that Killing Joke practice with one! Laney’s are good and cheap and will do you. Do not buy a Boogie, not ever, unreliable. I think you have to stay away from modelling amps as well, but there are some computer bases systems that are gaining a reputation, notably the Kemper.
From what you have posted I think you will need to augment your amp with some pedals on the floor. I know a bit about these too, but there is ample info on youtube.
My feeling is a Peavey would suit you at this time. Ultra or Bandit, as I am sure you will want hi-gain, and these are built to take it. Some amps cannot take that level of gain used in modern metal, the speakers fck up. Feel free to PM me if you have a deal in mind and I’ll tell you all I know. But its taken me 10 years to settle on an amp; have sold 2, 1 is for sale and have 3. But I still have that Peavey!
I know the guys at Killing Joke a bit and to overcome this problem, they just bought 2 brand new Marshall Vintage Moderns, I think one combo is around £600 but it will need some pedals to get the gain you like.
What amps are your heroes using? Diezel? Engl?
