Carvin X100B Preamp in Portable Pedal Format
The design criteria for the X1 was to deliver the sounds of the classic Carvin X-100B amplifier in a compact package with added connectivity. The result is a full tube preamp in a pedal format, able to fit in a carry-on or backpack. The X1 incorporates tube technology with simple, yet flexible modern features to interface with many types of gear.

5-Band Graphic EQ
The Graphic Equalizer is a powerful way to shape your sound. Each fader can be set for up to 12dB of boost (slide up) or cut (slide down) for each of the 5 frequency ranges labeled above. To enable the Graphic EQ for the LEAD or RHYTHM channel, use the small "GEQ" switches to the right of the faders. ON is indicated by the small blue LED (RHY channel) or small red LED (LEAD channel). The Graphic EQ can be set ON or OFF independently for LEAD or RHYTHM channels and switched from the (middle-left) "GEQ" footswitch. The LED lighting in the fader slots will add YELLOW in the center area when the Graphic EQ is ON.

Fully Buffered Effects Loop
Use the SEND jack to connect to an effect's Input. Use the RETURN jack to connect to an effect's Output. To use the LEFT footswitch to bypass the effects LOOP, set the small "BYP-LOOP" switch to IN for LOOP bypass mode. The green "LOOP" LED is ON when the LOOP is active and OFF if the LOOP is bypassed. Effects will be heard at the OUTPUT, SPEAKER and CAB VOICED jacks unless full BYPASS or LOOP BYPASS is engaged. Effects like compressor, envelope filter or wah pedals usually sound best when used between the guitar and INPUT jack. Effects can also be used on the OUTPUT or CAB VOICED OUT jacks.

True Tube Sound


I use it mostly as a preamp for my 64 Custom Hand Wired Deluxe Reverb-Amp, and also as preamp into a Quartet audio interface for a digital guitar rig. The controls are clear and intuitive, 4 stomps and a 5 band EQ, helping to get the sound shape I want with added drive and presence. It allows me the use of phones that the Fender amp lacks. Be prepared for some noise, depending on your setting. But those who favor warm tube sound will appreciate none the less.



Must have for the home studio


Have recorded many guitar tracks using this, just send into the insert of the amp to bypass the pre amp section of your amplifier. Also can record direct into your interface. With the 1 Amp out put you can practice quietly with disturbing the significant other, lol. Love this pedal and highly recommend anyone to purchase one.

I would definitely by this product again.


I use the X1 preamp on my pedalboard and connect it to my amp with the 4 cable method. This allows my to either use my amps preamp or bypass it and use the X1 as the preamp with my amps power amp, all tube of course. :) There is not anything to dislike about this product, it is awesome in every way and then some. Sam Ash was great to deal with too.



Great for travel or silent recording in a home studio!


This is great for travel or silent recording in a home studio! The fact that Carvin has not sacrificed any bells and whistles in creating this makes it perfect for home recording applications. I've always been a huge fan of the Carvin tone and now I finally have it in a small package. I'll be stowing away my 100w and 50w Carvin heads for now as I no longer play live gigs.



I can't believe it


I purchased this unit as a lark because of YouTube videos. Originally saw in premier guitar mag. This unit has revived my old tired preamps in my legend amps. There is no words I can describe that could explain but wow! The control and shaping of the tones outstanding. If you are looking for a preamp or even not buy buy buy! It will amaze you too. Clarity on clean distortion as you wish tone shaping awesome. It won't take long to acclimate the buttons but once you get the sound you want set it and forget it.

Old player still excited to play

Not sure if mine was a lemon or not


I bought this to run direct to the board for my live performances, mainly as a backup to my Engl Tube Toner Pedal Preamp. I bought it unseen/unheard. Once received, I liked the tone and the versatility of the Carvin. The features were exactly what I needed, particularly the three channels, footswitchable eq and the speaker emulated out. I'd describe the gain tones as meaty, almost Mesa like vs. Marshall. Not a bad thing at all. On the minus (and the reason I returned it for a refund) is that my unit was too noisy at idle, even with my guitar volume down. I switched back and forth between the Engl and the Carvin and despite the fact the Engl is probably 15 years older, it was WAY quieter. I ordered mine online and Sam Ash was super great about the return with no fuss. Kudos to their customer service. Honestly, had I the chance to demo one in store and take that one home (assuming it didn't have the noise issues), it would be a keeper at 4 or 5 stars. Maybe I just got a lemon, but at this time, I'm not willing to mail order another. I'm hoping to try one in a Sam Ash store sometime to give it another shot. I think it's worth a second chance.

The X1 sounds like my favorite tube amps on my ears.


The X1 is just beautiful for playing all my electric guitars through headphones at comfortable volumes. No need to shake the house with my tube amps for pleasing tones.

Possibly 5 stars


I am using this as a pedalboard amp with other pedals before, after, as well as is the effects loop of the X1. Last in my chain, I am using the Atomic Amplifirebox for an overdrive, reverb, and IR box. So far, I am very very pleased with the sound and feel I get. I recently switched to amp modeling. Amp modeling has come a long way as far as sound goes, but to me, is missing a certain feel that comes with a tube amp. This was my next choice and I am very pleased with the results. Very nice, warm, full tone and response. I have yet to use this as my live gig rig, so I cannot give it 5 stars until I have road tested its integrity and place in the mix. So far, I am very pleased. The videos I watched by SJP did not do it justice in my opinion. I would definitely recommend this. I will be bringing my pedalboard and guitar to my gigs and playing through our PA and possibly using my Headrush frfr when I do not have a monitor. Excellent sound through my Ownhammer impulse responses!

Sounds Great and Versatile ...


Has the features of the X100B with a little extra. Has a nice shapeable sound and can really help you thin the pedalboard given its abundant features. Works great in front of an amp. Captures the sound of an el34 X100B.




Legendary X100B in a stompbox!!!


I've got an original 1980s XV112 Oak (X100B combo) that'll take your head off, the X1 does exactly as intended: gives you the sweet, versatile tones of the Famous X-Amps at bedroom levels on its own or gig/concert levels when run in front of, or through the loop, of your favorite amp/power amp. The X1 can cover any genre on its own, but I love it combined with my Marshall JVM for a full range of classic and modern tones. Takes other pedals too!
