here's another tip:
i've been using this recently, DOD YJM308+Ibanez TS9(as Booster, dati gamit ko Boss BD2) and it sounds just right. but of course if a tube amp is available, 'rekta' na na, kakabitan ko nalang ng wah and the pre-amp overdrive(as bosster if needed) and that's it!
i agree, nothing beats the sound of an overdriven amp. problem is, bihira lang ang may magndang amp sa mga production ng gigs kaya ending is, to use pedals to simulate the sound that is needed..
