Brucegill Posted June 22, 2023 Share Posted June 22, 2023 (edited) Just got a GK Legacy 800w 1x15 combo in. Unfortunately it’s got a really noisy horn, almost unusable on high or low, all fine set to off. Fortunately I prefer it off anyway, but not really the tolerable on a new amp also a really weird fizz/whooshing noise on the decay of deeper notes. Only notice it if you let a note decay. sending it back, although I’m having to push for them to collect at the moment. price did seem too good to be true 🤣 Just wanted to check if these sort of faults are common? Sounds great apart from these issues. Also like the 1x15 more than I thought I would. It’s got way more power than I need Though…. any alternatives I should look at? The amp sounds great. Maybe go for a used head and another cab? Edited June 22, 2023 by Brucegill Quote Link to comment Share on other sites More sharing options...
Lozz196 Posted June 22, 2023 Share Posted June 22, 2023 Cheap & nasty tweeter most likely, I’ve had this happen in a couple of cabs and once the tweeter was replaced with a better one the problem stopped. 1 Quote Link to comment Share on other sites More sharing options...

Maybe I’m being naive? Edited June 23, 2023 by Brucegill Quote Link to comment Share on other sites More sharing options...
DGBass Posted June 23, 2023 Share Posted June 23, 2023 I have the 1x15 GK Neo cab with tweeter and its essentially the same speaker box spec as the Legacy 1x15 combo. The horn works very well in my cab, doesn't hiss or fizz and is quite controlable using a knob on the back. I'd be inclined to send the combo back for either a replacement or maybe something else. It sounds like the amp isn't quite working as it should🤨 1 Quote Link to comment Share on other sites More sharing options...
Brucegill Posted June 23, 2023 Author Share Posted June 23, 2023 (edited) @DGBass Many thanks. It’s doesn’t sound right for sure, but good to know they don’t all sound like that. The Fizz isn’t from the horn, it’s on the bassy notes as the decay. I can hear it better from the back the amp oddly (went looking to see if something was loose). On its way back to the seller on Monday. Edited June 23, 2023 by Brucegill 1 Quote Link to comment Share on other sites More sharing options...
DGBass Posted June 23, 2023 Share Posted June 23, 2023 One thing I've noticed with some GK amps is that the input sensitivity is quite high and having the input gain anywhere above 12 o'clock can actually overdrive the stage causing a weird fizzy distortion that sounds like the speaker is blown even at low volume. It can happen with a passive bass easy enough. The trick is to back of the input and use the master. Not saying thats what you have but might be of interest to try if the combo isn't already in its return box🙂 1 Quote Link to comment Share on other sites More sharing options...

Elfrasho Posted June 23, 2023 Share Posted June 23, 2023 tweeters don't hiss... amps do. if there's weird noises coming from it and its definitely not what you're sending to the input, sounds like the amps up to no good! 1 Quote Link to comment Share on other sites More sharing options...
