Pink Marble Spinning Musical Note



Premier Guitar reviews X-1 overdrive!
"Mulder Audio’s foray into overdrive, the X-1, has the beautifully made look of a pedal built to audiophile standards. Better still, is dishes heaps of dirty vintage-flavored goodness with a versatility that belies its streamlined design."
"The X-1 blended well with every amp and guitar combination I tried, thanks to its glowing transparency.
"The X-1 Overdrive delivers that coveted trifecta of overdrive traits: touch sensitivity, harmonic richness, and a wide gain range, from near-clean to filthy."

X-1 overdrive pedal VIDEO
"The build quality, musicality and mojo is strong in this one! It's super touch sensitive and you can chose between silicon and germanium diodes (or both!) which makes this overdrive pedal so versatile it's almost scary. With the Loud and Drive all the way up you move into fuzz territory. This pedal can be everything from an always on overdrive to a screaming fuzz pedal." Eirik Stordrange, Livingroom Gear Demos

X-Pedal cables VIDEO
"Is it really worth it - spending extra cash on the more expensive guitar cables for your pedal board? YES! And I've never been more sure since I installed the X-cables from Mulder Audio. They are simply the best cables out there. And of course, they are yellow. Who wouldn't want yellow cables on their board?"
Eirik Stordrange, Livingroom Gear Demos

What customers are saying!

"I've been putting the X-1 through its paces since I got it. Used it for a show on Saturday night - all the guitar guys who frequent my shows gave me big complements on the tone. I'm excited about using it for some studio dates that I have coming up. So far I'm loving it, especially the germanium setting." John M, West Chester, PA

"Ultra speaker cable is easily the best sounding cable I've ever used."
Carter Gravatt, Carbon Leaf

"Hands down the best improvement I've ever heard for my tone..."
C.S. Meriden, CT

"I am very appreciative for Gary Mulder to send me a pedal interconnect cable to try out. I have used his speaker cables for a long time and believe they are the finest sounding available.The Mulder (X-Pedal cable) seemed to have the same effect as the speaker cables. I.e. greater clarity, lower noise floor, and bigger dynamic range. To me it seemes almost impossible that a 9" little interconnect would have any appreciable difference. But it does. Pretty amazing."
P.O. Fair Oaks, CA

"Tried a Mulder speaker cable recently at the 65amps shop. We compared it to another "high-end" cable that is a lot more expensive, as well as the standard grade speaker cable that most folks would use with this sort of amp. Very impressed with the Mulder. The Mulder is the standard I will use when comparing other speaker cables."
Richard Robinson -- 65amps

"In my 67 Deluxe the X-Cable produced some very immediate improvements. First - an overall increase in dynamic range. Brighter highs, but not harsh. Fatter lows, but not squishy. Everything clearer and more present. It seemed like the same kind of results you might get if you had just re-tubed the entire amp with matched set of NOS tubes, but just from a cable! The whole thing just seemed clearer and louder. I'm a full-time touring pro, and these cables will be going into my road amp - a Dr. Z Maz - very soon!"
Chris Soucy -- Sally Taylor / Stephen Kellogg and the Sixers

"I tested using 76 Hiwatt, 80s Marshall JCM 800 and Fender Bassman. The difference was instantly noticeable. Highs were crisper without harshness and overall dynamic range sounded much wider. Really a serious improvement! Like my amp needed to blow it's nose! Anyway, as I am sure you know, these cables speak for themselves and should be part of any serious tone-hounds rig!"
Bill Nash -- NashGuitars

"I got the 18" x-cable for my TIM combo and it is a DRAMATIC difference !! More open top - NICER smoother top end w/ any harsh frequencies just vanishing !! Nicer bottom - just overall a significantly CLEARER and more pleasing sound - transient response w/ a hard attack of my telecaster 's bridge pickup sounds smoother w/ out losing that KERRANG !!! I was so blown away - I yanked it out and put it in my '64 deluxe reverb and same thing - just simply better - NOTICEABLY !!!"
Dan Strain, Professional Guitarist -- Nashville

"I rewired my Matchless DC30 with the Mulders and couldn't believe my ears! Amazing what these cables did. The trademark Matchless swirl is more evident, the separation between the two different speakers increased and it's almost as if I play in stereo. Also, some of the rough edges are gone and the sound is more musical, flowing and together. Even though the frequency extension seems to have increased, this was not done by sacrificing sweetness and musicality. Nice!"
T.W. Athens Greece

I A/B'd the (high-end competitors) cable that came stock with the Carr Rambler with your X-Combo cable, and there was certainly more mid-range clarity, and woodiness to the tone. The top end is sweet and round, but never harsh, and the low end snap is just what I was looking for. I am very pleased to say the least!
