Personalised multi-point setup included

Before dispatch, your instrument will be treated to a full setup. That's not a quick tweak, but a full multi-point setup by an experienced guitar technician who will check and adjust every single thing on your guitar, bass, ukulele or banjo to ensure it is performing at its absolute best.

This is not a quick process but we believe every instrument should go through our process to acheive an exacting standard of playability.


We start with the frets on your instrument. All guitar necks move and change over time so we will make sure that your frets are nice and flat as we go up the neck. We don't want any high or low spots as this will mean your guitar will need a higher than optimum action and potentially suffer with fret buzz.

We check and properly profile the playing surface of the frets and then make sure the fret ends are finished off properly. The fret is then polished to ensure smooth string bending.

Truss Rod

Then it's on to the truss rod. This metal rod differs from guitar to guitar (some guitars such as classical guitars don't usually have a truss rod!) and basically controls the "relief" or curve of the neck. Not enough relief and your strings won't have enough clearance over the other frets when playing. Too much relief and you'll have a high action which gets worse as you go up the neck.

The heavier the strings then the more the truss rod needs to work. Proper adjustment in the workshop means that the action will be just right for the strings fitted to your guitar.

Top Nut

The top nut is super important and is one of the two open contact points of your guitar. The technician will check and cut each slot to make sure the strings both run freely but are not sitting in a slot that's too big.

The top nut also plays a big part in the action of your guitar so we'll hit that sweet spot between too low and too high.


Another really important part of your guitar!

On an acoustic, the saddle is cut to the correct height making sure the bottom is 100% flat and straight. This means the string can transfer its vibration properly into the body of your guitar.

For electric guitars, the saddles are adjusted to ensure your intonation is perfect. We will also match the saddles to the radius of your fretboard.

Bridge / Tremolo

The bridge affects the break angle and string height of your guitar and is also responsible for holding your saddles.

For a guitar with a Floyd Rose tremolo system or similar, the spring tension has to be just right to allow the tremolo to return to its "zero point" and keep everything in tune.

For guitars with standard tremolos, we can set it to float and be used both up or down like a true tremolo or we can lock the trem block back so the tremolo will only go downwards.... the choice is yours!


Intonation is the measure of how in-tune the guitar string is across the length of the fretboard and a guitar with badly set intonation will get more and more out of tune as the string is shortened when you play.

Tiny adjustments are made to each string where applicable to adjust its length and ensure that the intonation is set just right.

Overall Action

Once all the above has been completed, the guitar is checked for playability and fine adjustments are made. This step brings everything together and means your guitar will be set up optimally.

Machine Heads

Every machine head is operated and checked for function. We need to ensure that the machine heads operate smoothly.


All the functions of your guitar are checked to ensure everything is working as intended.

For acoustic guitars we will check the functions of the EQ system and controls as weel as check the internal cabling and jack socket.

For electric guitars, all the pickups are checked for function and tonal response. All controls and switches are operated to ensure they are functioning properly. The jack socket is checked.

Other Parts

All other parts such as strap pins, bushings, tuning buttons etc are fully checked.


All our instruments get the same premium treatment wether you purchase online or instore.

If you have purchased online, your guitar will be carefully packed ready for dispatch. You will receive a tracking link via email.

Happy playing :)

The BOSS Katana 100 MkII is the latest incarnation of the hugely popular 100 watt, 1x12" guitar combo. BOSS have turbo charged its core platform with more sounds, more effects and more features...and thanks to its adjustable power control, taking you from 100w to 50w right down to 0.5w, it's a superb amp for stage, studio or home!

This MkII version pickups up form where the original version left off, with 5 primary amp characters; Clean, Crunch, Lead, Brown, and Acoustic (for acoustic-electric guitars). Clean brings natural and transparent tones, Crunch gives added grit, Lead will take you from blues solos to searing rock leads, Brown is derived from the Waza amp, great for high-gain tone and finally Acoustic is optimized for electro acoustic guitars. The tonal options have now been extended, with each of the 5 primary amp voices featuring newly voiced variations, fundamentally giving you a total or 10 amp characters (double the amount on the previous generation).

Utilizing BOSS's Tube Logic approach, the Katana 100 MkII is able to produce the authentic tone of genuine tube amps, with the tube like feel and sound changing and becoming richer as the volume increases. The handy Power Control allow you to achieve that cranked amp tone and response at super low volumes, great for home use.

BOSS have also improved the effects section, now giving you 5 simultaneous effects categories. The 5 independent sections Booster, Mod,, FX, Delay, and Reverb come ready with 3 variations in each, a total of 15 ready to play effects. Connect to the BOSS Tone Studio and you can delve much deeper, customising the sections with over 60 different effect types, with access to changing the order of the chains and more! Once you have you amp character set and selected your effects setup you can store your custom setup one of the 8 Tone Settings for instant recall.

Stereo Expand is a new feature that has been added to this MkII model, allowing two amps to be Katana MkII 100 sounds great, but two at once is even better! You can control everything from the master amp, with stereo effects like chorus, delay and reverb being distributed across both amps for a huge immersive sound.

If you have a favourite preamp or multi-effects unit the Katana 100 MkII can also function as a standalone powered cabinet. Simply connect to the rear panel Power Amp jack, which will bypass the amps own preamp and effects, whilst still letting you tap into the Tube Logic power section.

Other features include the USB and phones/recording outputs which feature mic'd cabinet emulation, allowing you to send amp ready tones straight to your DAW or headphones. There is also rear panel connections for a footswiches, an AUX in and a Line Out.

For added functionality you can add an optional GA-FC foot controller. With the six footswitches you can easily recall Tone Settings or independently turn the five effects sections on or off.

BOSS really hit the ground running with the first generation Katana amps, and now, with these improved and updated MkII models, things get even better!
