You have a couple of ways from here depending on the fx processor you're using. What brand and model are you using? The easiest way would be: Invective Loop 1 send --> FXP (processor) input --> apply effects --> FXP output --> Invective Loop 1 return --> MSDI to audio interface If you have multiple inputs and outputs in your multi fx processor, you could do the following: Guitar --> FXP --> Apply effects before amp (Distortion, Wah...) --> FXP Output 1 to guitar innput on the Invective --> Invective Loop 1 Send --> Input 2 FXP --> Apply effects like Reverb/delay --> FXP Output 2 --> Invective Loop 1 return --> MSDI to interface. The second one is more complicated, but allows you to place every effect where it needs to be (before the preamp, or in the fx loop). Make sure to adjust all signal levels accordingly. Be super careful doing this on amps where the FX loop comes AFTER the master volume, otherwise it will be very, very loud if you do a mistake.

​@TobiasJust Ax fx 8 ,I want to utilize 4cm ,if those signals come through the msdi that would be my preferred method.

@@scot483 I'm not too familiar with the Axe FX 8, but you could do something like this: - Connect your guitar to the Axe FX Instrument Input - Connect the Out 1 (pre) of the Axe FX to the Invective guitar jack - Connect the Invective FX Send 1 to the In 2 (Post) of the Axe-FX - Connect the Out 2 (Post) of the Axe FX to the Invective Return 1 - Connect the MSDI Output to your recording interface The problem is the Axe FX doesn't have two separate loops (basically it's 1,5 loops). With devices like the Line 6 Helix you have a guitar input and two sends / two returns, which allows you to feed the MSDI back into the Helix. Unluckily you can't do this with the Axe FX 8 because it has not enough return jacks on the backside. You can still use various preamp models of the Axe FX, though you will always hear it through the Invective Poweramp (which is fairly neutral sounding to befair) but colored by the MSDI speaker simulation. Keep in mind the Invective MSDI tries to mimic the impedence curve of the connected guitar cabinet, so connecting different guitar cabs and speakers changes the sound of the MSDI cab simulation to some extend...

That seems a but steep for just changing preamp tubes, did they do any other work? I actually prefer the sound of the 6260 to the 6505/5150. I have mostly Marshall's now, jvm210, jcm2000, jcm800 but I still have two first gen 6260s (modded and unmodded), they hold their own.

Yes, the tech did a full service & clean, tubes are really expensive here in Perth so the amp is a keeper now, lol. I'm a Marshall guy also, JTM45, sold the Kerry King JCM 800 and the classic VS100 heads and bought a Ceriatone hot rodded Marshall, a 100w Leviathan and man it is the bees knees. Keep Rockin' bro🤘

Thank you Jeff!

Thank you! It depends on what you'll want to do with the amp Technically you have a lot of different ways to go with different pros and cons: Using the MSDI: - You need to connect a cab to load the power amp section, otherwise you'll roast your amp - The MSDI always provides a miced cab sound, so you're not allowed to run it through a second cab emulation (Like the one of your Tascam mixing desk), otherwise it will sound bad and dull Using the MSDI with a load box: - You connect a load box instead of a guitar cab, so the amp is totally silent even if cranked - Then you can use the MSDI signal for silent recording or to please the FOH with a silent stage on live gigs. - Downside: The MSDI has a unique feature that tries to emulate the cab that has been connected. When you use a cheap loadbox with a resistive load, the impedance curve doesn't match to real guitar speakers, resulting in different tonal behaviour in the bass, mids and heights. This effect is worse the more you crank your amp. However, there are reactive load boxes which emulate impedance curves of specific speakers, which you might want to consider. But I noticed there are differences in between them and some sound brighter, some sound darker. Using a load box without MSDI: - Load box to your guitar amplifier, so it's silent - Usually good load boxes have a XML jack to get the signal of your amp on line or mic level. However, this will sound bad, bright and harsh without a cab simulation - You'll want to run this signal through your Tascams cab simulation and then you have a finished sound. This is a good option in case you should not like the MSDI sound. - You can go even further by buying some devices that can load IR's (Two Notes CAB M Plus) and use these, so you can use your favorite IR's on live scenarios on Tube amps. This is good if both the Tascam Cab simulation or the Peavey MSDI are just not your cup of tea... Last solution: - Keep your cab connected to your Guitar amplifier - Activate the FX Loop and connect your FX-Send to your Tascam guitar cab simulation - Leave the FX return on your amp untouched! - Amp should be silent if the FX loop is not parallel, but you got a signal for cab simulation. - Downside: You're not going through your power amp section, which will have an impact on your tone. You have no power amp distortion, saturation, SAG and all that stuff that you like when cranking up tube amps that are designes for. - BUT: The Invective is OK to be used that way, since the poweramp section was designed to not sag and distort a lot. The main tone comes from the preamp section. It will sound a little different though, since just running through the power stage the tone will change, even if you don't crank the amp. Realistically you have a million more options, as there are devices to emulate power sections, so you could buy and use these as well. But at some point you'll end up using 10 different devices instead of a real guitar amplifier and at this point you could also just use a modeller like the Line 6 Helix or whatever is available out there... Much to read, but I just felt like I have to take my time because I'm sure you'll want to have the best sound possible. So here you go! Cheers Tobi

​@@TobiasJust Just the info I needed! Excellent timing. Hope your 2023 is blessed with heavy chuggz and sick riffs.

thank god! i just got a V3 yesterday and didn't think something like this existed! the V3 can be notoriously fizzy. i can't wait to get this thing!

No, unless you can switch off the power amp you still need a load connected. Don't ever run it without a cabinet or load.
