Anyone using a Gallien-Krueger 250ML as desktop amplifier?

    I am currently trying to make up my mind between the Yamaha THR old or new series of desktop practice amplifiers and the (for me) cheaper and possibly much better alternative of using a GK 250ML (around 250€ used here in the EU).
    Although power is not a priority for me, the GK’s 100w of stereo power makes it capable of gigging, compared with the top of the range THR30w, and only 10 or 20w on other models.
    The GK also has its own FX loop, as well as a stereo Aux in (but no separate volume control).
    What I don’t know is how the GK compares with the THRs when used with modelling software at practice levels? I know that is where the THRs excel, and this is an important consideration for me.

    My second question is about the stereo separation from one channel to another - how well defined is this in the GK compared to the THRs?
    Finally, I also have a question about the 6.5” Pyle speakers fitted to the GK 250ML. Since at this age the speakers will most likely need to be replaced, would it be worthwhile replacing them with full range speakers, and if so, what would you recommend? I assume that both the GK and Yamaha speakers are guitar voiced speakers?

    One of my roommates in college who was quite wealthy got a new 250 ml in 1988(?). I've always said I'd jump on one if the price was right. Low volumes may be an issue as his always seemed like a racehorse in the chute.

    I've seen a GK 250ML used as a monitor on an amp repairmans workbench. Must be a pretty good reference system.

    I doubt you could get good stereo separation with that, you'd need to plug in external speakers.

    Years ago I played with a trio (hammond B3, Drums & Guitar). We had a booking agent that would send us everywhere. There were times we played in places that were so small we were right on top of each other. I carried a GK 250ML with me for such scenarios. I would set it on top of the Leslie cabinet. It was a great little amp.

    I haven't played through one in years, but I thought they were awesome, although quite expensive, back in the day. Here in the US they seem to be very thin on the ground, and finding one is rare.

    Had one in the 80s and it was great for the chorus sounds but got kinda empty for anything else. Would be fun to try one again in hind sight...

    I have one. Replaced the speakers with modern Pyle "mid-bass" speakers from Amazon. They work pretty well full range, too.
    As an amp through the guitar input, it sounds great if you're looking for *that* sound (80s compressed and processed with effects). It can do the power amp and speakers thing pretty well too. I have used it as a monitor for modeling pedals, both for guitar and lower volume bass in low to mid sized rooms. Pretty amazing range for a shoe box-sized rig. Sounds okay in a band context, but I much prefer an actual amp.
    Very little stereo separation unless you're right in front of it looking directly at the gap between the speakers. You can run extension cabinets easily from the speaker outs if you need more separation. Sounds pretty cool that way.

    Mine is still in active service. When I got tired of lugging heavy gear, I paid a good price for this amp. It still can be a lot of fun. Later, I had it on the desk where I tried to focus on learning songs. It now sits in an area where about half of my amps are, and where I tend to spend half of my time playing or learning something music related.

    It sounds really good through a couple of Greenback 16 ohm cabs, but I foolishly sold one of those cabs trying to gain space.

    At one time it was my main amp for twenty years. It has been with me about 35 years or so. For what I would get for it cash wise, I might as well keep it.

    I also have the GK keyboard amp and a 200RCB Bass head. My keyboards are gone, and I should likely sell that amp. The bass amp is still extremely relevant for practice through a 210 bass cab. image.jpg image.jpg
