Thank for that, I hadnt even considered Impedance, thats a very good point! Anyway... the plot thickens...the unit works fine on my other amp.... Ive been through and checked all the levels and they are se same on both amps so go figure... JCM 800 with added tube effects loop = Happy HXFX Valvestate 8080 combo = HXFX squeals like a pig! for obvious reasons I'd like the option of being able to use a small combo rather than a head & 4x12... I'll take a look at the loop schematics and see if anything jumps out impedance wise. I wonder if its somthing woth this specific amp.

Ok, I am really struggling to get a usable signal out of this setup, I've got it cabled up in the normal fashion, and currently am using a spignal path with ONLY the loop in it. the problem im getting is as soon as I try to use the loop with the guitar amp preamp i get feedback/oscilation. Ive got the guitar input set to instrument level ( obviosly) and no mater what combination of levels I use on the loop i cant get reasonable audio level back inte the amp without oscilation. Ive actually gotten to the point where i am measuing the effects loop levels on VU meters ( analog stand alone ones) to fault find this to no avail. With just a VU meter patched in the amp effects loop i am seeing Line level signal (+4dbu), but am unable to put anything like this level back into the amp from the HX without oscilation. to get the oscilation to stop i have to ramp le level down by around 20dB, in whoch case I get no real usable volume out of the amp.

Nice solution, Ive been looking at probllem for y HXFX this but had not seen the Falken. in terms of current, the HXFX runs at around 1A, but needs somthing like 2A at start up (I did measure it, but cant remember the exact figures) Another solution that, i am considering is using bike light battery packs, they will deliver the current, but are only 8.4v so I need to check the function of HXFX at lower voltages. I already use these as bike lights, so know they will deliver 1A for at least 4 hours, and they are cheap! I should add, you will obviosly need to check/swap the polarity! or you will fry somthing!!! https://www.amazon.co.uk/BSWAN-Rechargeable-13200mAh-HeadLight-Taillight/dp/B07K9RDYSB/ref=sr_1_1?dchild=1&keywords=cree+bike+light+8.4v+battery&qid=1596969062&sr=8-1

Bump, is there anyway to find the serial no? I have bought a 2nd hand one and would like toregister it, but the serial no label is mostly missing so only the last few digits are readable.

Does the HX Effects use the same foot activation switch as the helix? I have a where the Plunger has poped out an gone Awol, Ive found the below and m hping the Helix one is a drop in replacement. https://www.fullcompass.com/prod/282573-line-6-50-03-0129-foot-switch-assembly-for-pod-hd500x https://www.fullcompass.com/prod/282573-line-6-50-03-0129-foot-switch-assembly-for-pod-hd500x
