The question is about a HD 130 - a bit off topic, but I hope you don't mind ;-) My HD 130 has got the same panel and inputs as the picture of the amp on the homepage of this site. For some reason, I have only used the input Jack labeled "1" Now I found out, that the "2" gives a different sound/volume level. Can anyone explain the difference between the two ? Cheers Jens | ||

The second input jack is different in that it is coupled to the circuit using a larger resistor. This is done for a couple of reasons. The #2 jack can be used by itself for high-output "active" guitars or "hot" pedals. It can also be used as a "channel coupler". If you plug your instrument into Jack #1 you can use the #2 jack of the same channel as a link to Jack #1 on the OTHER channel. This puts both channels of your amp in parallel and offers a variety of intersting tonal capabilities not possible with a single channel alone. | ||

that was the most useful info ever thankyou so much i am looking fwd to jamming tommorow i am new on the site my name is carl from melbourne aust. this site really is awesome, i will brag in the brag section ok? | ||

You bet...brag away! The clue about putting both channels in parallel is essentially the same method that people used for wiring multiple older Marshall amps together on-stage for that "wall-of-sound". The interesting thing about using both channels of a two-channel amp rather than two completely different amps is that the signals mix and cancel electronically inside the amp which cause all sorts of interesting tonal possibilities that are completely controllable and independent of room acoustics! Using the amp this way is like having your tone control section on steroids! Try it, you'll like it! ALL of the controls make a difference and are interactive... a real tone candy-factory! | ||

I have a 212-75 and found a combination I like. I come out of the left/right outputs of my delay to the #2 inputs on each channel (I found #1 to overpower too much). I roll off the volume of my guitar for a nice, thick clean and pour it on for a serious crunch. | ||

if jack #2 can be used to connect to jack #1 of the 2nd channel does that mean it can be used as a line out for recording purposes or would it be to strong of a signal? | ||

Well if it's going into a line level input, I would assume it is a line level output. | ||

You could dial down the signal but it would be dry and straight guitar-the amp really wouldn't be driving the signal therefore you would have none of the effects of the amp coloring it. It would only get what you were putting into it and that usually isn't very good for guitar. Mike | ||

Using Jack 2 as an output gives you LESS signal than the guitar puts out and it would be closer to a microphone-level signal than a Line-level signal! Steve | ||

Also, does the "channel coupler" work if done in reverse of the way you explained (i.e. starting by plugging the guitar into Jack #1 of the Reverb/Tremolo channel)? Does it also work when plugging the guitar into Jack #2 and jumping from Jack #1? Can't wait to try this out! -Adam | ||

I know this is old, but I wanna try it... Adam, did you try it? |

HD one thirty effects in the bridge?
Is it possible to insert effects like fuzz or distortion between channels when bridging them?
HD 130 Head input jacks
Hello Everyone,
Does anyone happen to know the answer for the question of Josue Roberto:
"Does this only work when using "Hi" Power. Also, does the "channel coupler" work if done in reverse of the way you explained (i.e. starting by plugging the guitar into Jack #1 of the Reverb/Tremolo channel)? Does it also work when plugging the guitar into Jack #2 and jumping from Jack #1?"
Many thanks in advance,
Balázs
Only works on some amps
Jumpering the channels only works on some amps. The 2275-130/65 and 2475-130/65 with reverb+tremolo inverts the phase on the second op-amp on Channel 2 so you get signal cancellation if you try to jumper.
2100-65/130 amps and the later 2100-150/75, 2275-150/75 and 2475-150/75 will allow jumpering of channels. The hi/lo setting only affects the power amp so jumpering will work in either setting. Jumpering can go both ways - when you use both jacks in one channel it doesn't matter if input 1 or input 2 is the 'in' and which is the 'out'. The amp doesn't care which channel you consider '1' or '2' - that's just a human user issue, so to speak. Just try experimenting. I could totally see a 2100 amp with a reverb device of some sort between the channels so you can have separate eq and volume for the wet signal.

Thank you Lars,
Thank you Lars,
Mine is a 2100-130. It works just as explained by you. Pure magic!
