Also I'm not sure whether middle position in GK corresponds to 'neutral' frequency response. And tone controls modify the signal even more. You have to understand that signal from bass guitar is not a sinewave.

If you get clean sinewave at full power (I repeat: at full power), there is nothing wrong with the amp. The problem only seems to occur when playing low frequencies (bottom string) through the amp.As I said, you need to verify the amp in test environment (generator->amp->dummy load->oscilloscope). The sine wave from the bass is good both at low and high frequencies.

Running a tone generator into it produces a clean wave at 100hz & 1khz. The proper way to do it is to find out what is wrong and only then start spending money :-). The problem only seems to occur when playing low frequencies (bottom string) through the amp.Ĭontour is off & all tone controls are set mid way.So you already spent a lot of money and the problem is still there. I have already replaced the speakers (last post was a follow up from a month or two ago) and am having the same problem.Ĭontour is off & all tone controls are set mid way. If it's OK, you can verify the amp with external cab (you can borrow it instead of buying new speakers). Before you start replacing speakers you have to verify the amp. The signal looks like this because the input is not sinusoidal wave and maybe tone controls are not set to the middle position.

The proper way to check the amp is to use a tone generator and a dummy load. A symmetrical sinewave sounds like cheap keyboard. If anyone has similar configuration - I'd welcome your comments on which way to go. Which would allow me to run the full 300w of the amp into the combo speakers.Īny pointers welcome, replace the speakers + leave room for an extension cab in the future or is it not worth it & should I replace the speakers and forgo the option of an extension cab in the future. Replace the existing speakers (Eminence LEGEND BP102 (8Ohm 200w) wired in parallel to drop the total load to 4Ohms. Replace the existing speakers (have seen some Eminence LEGEND BP102-4 (4Ohm 200w) which look like would make good replacements and still leave room for an extension cab later on if I wanted.Ĭ. Add an extension cab (not sure if I want to add an extra cab at this stage as the amp should be capable of delivering more power before the speakers start breaking up as it is) + it's heavy enough as it is.ī. If the existing speakers are breaking up at half volume, what route should I take:-Ī.

So I'm wondering what to do as in my opinion, the built in speakers should be easily powerful enough to handle the 180watts the amp is advertised to deliver into 8Ohms at just about any volume + when plugging in an extra cab (1x15 or 2x10) to take the load down to 4Ohms, the amp should then be capable of delivering it's full 300watts. It's fine at lower volumes - just the attack when turned up. My problem is that whenever I play it at half volume (or more) the speakers start popping when I pluck the strings. It's rated at 300w into 4Ohms, has built in 2 x 10' speakers (total 8 Ohm load) and a spare jack on the back for an extension cab. maybe if your into death metal or something.I have a Gallien Krueger Backline 210 combo (bought late last year when I downsized my full rig to something more transportable). bass players don't really need it, but GK claims that bass players are starting to experiment more with it. But, that said, if you have even a decent bass, you can get some really nice sounds with it. As alot of people noticed, the GK amps seem to be really pure in tone, and don't make a bad bass sound good, they just make it louder. You can really muck with the sound, but you need to have a good bass. I tried a Hartke kickback 15' at a really big church I played at and it wouldn't keep from distorting no matter how gentle you were. It doesn't rattle like my last one did, but it does distort when played really hard, but its not a fuzz-filled staticy distortion, its less than any other similar amps I played. It seems to really like the p-bass sound, but if you pick it, you may want to use the 10db cut so the preamp wont clip. I use a Peavey P-bass replica, currently, but am switching up to a Fender P-Bass special.
