Ok, i am in a new band. The band is a quite good one with a heavy sound. think to Judas Priest, classic heavy metal meets The Gathering and stuff like that. i have an Ampeg SVT410 Hen cabinet which is rated at 8 Ohm and i am visiting all the shops near where i live to find an adequate head. the band i formed by a loud drummer a guitar player equipped with the classic marshall half stack all tube 100w, there is a female singer and a keyboard player. i dont' have a lot money to spend and i am taking a look at the used heads, i found: Hartke HA 5000 list at 450 Euro which is 170+170 at 8 ohm (too weak?) Ashdown MAG 250 list at 290 Euro which deliver 250 W at 4 ohm Laney DB 400H list at 400 Euro as you can guess i am not lloking for a great sounding head. i only need a enough powerful head that can go togrther my cab. music it's quite heavy, so i need power. i'll go on taking a look around. if anyone has experience with the heads i named, you are more than welcome!
