I'm a senior in highschool and have been playing for a year and a half, and over the last 2-3 months a group of friends i jam with has become alot more serious and we are playing more often, which is good. The problem is to be heard over the drums and guitar i have to crank my amp up all the way.(I am using a laney hardcore max 1X15 combo that i bought off a friend, its the only amp ive ever owned). When i turn my amp up that high it distorts and generally destroys any thing resembling tone. My bandmates and i have taken to calling it the serial rapist on account of the tone raping. Anyway im in the market for a new amp, and i want atleast 300 watts (i think the laney is 100 but am not sure) so i dont have to push it so hard and can maintain a decent tone at high volume and hopefully can play some small gigs (if the band goes that far). I have very little money though so here come the questions: Of these amps, wich would you guys recommend http://bass-guitars.musiciansfriend.com/product/Ashdown-MAG-300H-300W-Bass-Amp-Head?sku=485030 the ashdown seems good but i know nothing about the brand. http://bass-guitars.musiciansfriend.com/product/GallienKrueger-Backline-600-Bass-Head?sku=482534 ive heard good things about gk but does anyone have firsthand expirience with this head? http://bass-guitars.musiciansfriend.com/product/Behringer-BX4500H-Ultrabass-Bass-Head?sku=481090 and the behringer, i either hear that these are excellent or complete crap, but im very tempted by the higher watts for lower price thing, so any expirience would be great. Question part II In all likelyhood it will take me forever to save up the money for a new amp and cab, so can i just buy the amp and use the 15 that my laney has (it has a normal 1/4 plug and is 8 ohms) or am i asking for a blown speaker because i dont no the power handling on the speaker? Again thanks for any advice.
