Hi Everyone, first thread here and I'm having great time reading all opinions and reviews about amps and basses. I hope to find help from owners and ex-owners on the amps below. Sorry for any English mistakes. I am a keyboard player and I have been studying and playing bass on my own for a long time, until recently I bought a Fender Mustang PJ. I played in 80's and 90's rock bands and hopefully soon set up a band or join one as a bass player. I have good technical knowledge about amplifiers, their settings and effects and I am currently looking for an amplifier to play small stages, but with the possibility of expanding easily if I need to play on larger stages. Below are some amps that I'm watching and would like the opinion of anyone who has ever played in any of them. I am open to other suggestions as well. Unfortunately the sellers are not from my city and I can not test the amplifiers before buying them, so any help is welcome. I've read all TalkBass threads about those amps but I like a more directed opinion based on my needs above. I'm toward heads/amps that includes: Compression, Graphic-EQ and aditional external cab support. (prices are in dollars converted from values here from Brazil - yes, music equipment here is expensive) ----- Portable options in 2x10 $660 = Peavey 210TX Combo $710 = GK Backline 210 $890 = Hartke HA3500 ($420) + Hartke 210XL ($470) There's also some bigger options I'm considering: ----- Options in 4x10 $950 = Hartke HA3500 ($420) + Hartke VX410 ($530) $1,050 = Hartke VX3500 PS1: All of them are used on good conditions, except for the VX3500 that is like new (almost never used). PS2: Peavey and GK are manufactured in the USA, Hartke in Korea. Should I be concerned about this? PS3: Hartke's are easy to find, there's a lot of them selling everywhere in Brazil. The Peavey 210TX and GK Backline combo are just one each. PS4: If you are curious about other amps/head like Carvin and Ampeg, here's a list of some local market pricing research: Thanks in advance!
