So in answer to your question with regard to filters... I've now been using the GT Core for a week and getting my head around it's various features and possibilities. The EBS IQ filter pedal I've currently got on my board (pictured above) is one of the very best analogue filters I've come across - almost on a par with 3Leaf filters I've had the privelege of owning, and considerably less expensive.

 

I've set up a filter patch on the Core, [using the Touch Wah fx in band-pass filter mode - in case of wider interest] which gives me the choice of up or down filter. I've also included an octaver, but just with up-filter, to thicken up the sound. Really like what I'm hearing on both up-sweep and down-sweep. And the excellent EBS... well that's just been taken off my board and will likely be appearing in the for-sale section in due course 😊

 

 

That's ace, really tried but struggled to get anything dialled that i liked. I didn't have a filter pedal to compare with though which didn't help!

Newbie Q: if I put a pedal in the send / return loop of the Core am I correct that it can be set to run in parallel and won't be impacted by any of the fx in the Core? I'm thinking that would be the ideal set up for little drum pedal for home use.

Can't remember what options there are in the FX Loop block, ultimately you'd just be using the return of it anyways.

 

If there's an option to blend the FX Loop with the original signal, you could stick it at the end of your chain after all your fx, amp and cab stuff with the direct signal blended in.

 

Otherwise you could do the same with a parallel divider at the end of the chain with the FX loop on one side. 

 

Definitely doable though.

More of a question than a tip or idea.  Am I right in thinking IRs are only active on outputs set to recording?  I want to use just a couple of the effects before my amp in one of my bands.  If I turn the amp module off and don't have recording set on the output, then I just get the effects, right?

[matybigfro]

Close but not quiet spot on.

 

Speaker simulation (how boss refers to it's own ir's) or IR's are tied to A.I.R.D. amp blocks (how boss refers to amp simulation) so when both amp blocks are switched off there is no speaker simulation. Output selection is irrelevant in this configuration regardless of how it's set speaker simulation is also disabled.

 

Alternatively if you have output set to recording in the speaker simulation block you can then also select the speaker type as off and then you will have no amp simulation regardless of whether the amp block is on or not.

[clauster]

Cheers, exactly the advice I was after.

Just picking up on your excellent post on the "distortion that keeps the 'thump'" post:

For me 'blending' only works if the clean path has a LPF and the filthy path has a HPF in front. In stompbox-domain that's a lot of pedals for a distortion sound (... so yeah, Boss GT Core : )

 

By the way, to me the X-Bass distortion on there is quite good. I played in a loud sludge band and from the distortions I tried (several blended options and also Darkglass pedals) this X-Bass was absolutely the easiest to fit into a mix and without loosing 'thumb' (if by that you mean the low frequency portion of the attack, the part that differentiates loud bass and loud guitar). On it's own it sounds a bit boring, not spectacular at all. Because of this it took me a long time to actually try this one.

 

Good luck with your endless search, do not give up, do not leave the distortion to the guit@ri$ts !!! 😃

(certainly in recordings there will be distortion on the bass to get a huge sound ?!)

 

I'll need to give your recommended X-bass distortion a try out!

 

I've been using the AIRD Preamp Orange stack which gives a very juicy fuzz that I'm liking a lot.

As we were discussing, so much more weight to it with a clean blend parallel path, and with the EQ in the +125Hz bass/low mids given a boost on both paths, combined with using a comp as a sustain on the fuzz path but something much more standard on the clean blend path.

I've been using the Fat Tube bass preamp with no cab sim as an overdrive/fuzz with great success on my GX-100. I've also got some general EQ going on. Boosted around 1k for a bit of grind and cut some mids around 350Hz. Also worth a try...

Thank you AlKrow and MichaelDean, I always forget to use the amps as distortion units! I should experiment with those again. Thanks for the reminder!

Boss Slicer Fx

The one on the core is very cool, you can set parameters like Pattern via assigns to oscillate through options etc to give a cool glitch effect 

 

Just pulling the chat onto here to avoid derailing the pedal board thread too much!

 

I've attached a little Mosky dual switch onto my GT 1000 Core, a while back, which then gives me an additional two i.e. a total of four configurations per patch.

 

I'm sensing a multiple config Slicer patch needs to see the light of day on my Core!

Anyone managed to get a decent pitch shift +/- 1 or 2 semis on their Cores?

 

[Al Krow]

I've taken the liberty of widening this thread to GX10 users given the similarity of the patches and Boss editing software.

And in answer to my own question, have managed to get some decently usable pitch shift patches on my GX10 ( and making me ponder whether to hold onto my dedicated Boss pitch shift pedals - OC5, XS-1 and XS-100?)

So is your GX10 pitch shift s good as the XS-1 (and 100)?

Nope!

 

But it's surprisingly usable for +1 / -1 and +2 / -2 semis (using the pitch shift fx) which is predominantly what I'll need to handle key changes between our soprano and alto singers who separately front the band. (Not sure why I didn't discover this on the GT Core?) 

 

I wouldn't want to go further, whereas with the dedicated pedals you can go down/up a bit further to +/- 3 or 4 semis.

 

The poly octave down is good!

 

There's a few options for octave up on the GX10 (which the XS-1 and 100 do very well). I found a couple of them (Harmonist and Pitch Shift) are pretty bad when used for this.

 

But the "overtone" patch is very usable for octave up. It allows you to simultaneously have octave down and up,  with independent volume levels for each, very similar to the OC5, which gives a tasteful thickening-up of the bass. But additionally on the GX10 you can then also add in a detune and, very neatly, set the expression pedal to control the volume of eg just the octave up (with min and max set which ever way around you want to use the expression pedal), which could be fun / useful live.

Being able to assign the expression pedal to dictate the amount of gain on drive patches to take it from mild to full-on drive is also very neat. 

 

Essentially you have the option of assigning the expression pedal to any parameter of any particular fx in the chain. Possibilities are endless...

 

All this stuff is obviously do-able on the Core with an external expression pedal, but having one on the pedal itself definitely focuses the mind on the additional possibilities.

Yeh, thats the same on the ME-90B as you would expect (same company), just that the pitch shift isn't in the same league as the XE-1, certainly not up to a couple of semitones below a drop D as a solo instrument live.

Just had a quick play on with pitch shift set to -2 semis fully wet, and GX10 seems to comfortably handle taking down the low E by a couple of semis in terms of a usable-in-the-mix bass. What are you finding with the ME-90B?

Oh its more like a wammy effect, in fact it is only available on the footpedal, but it is too electronic to use as a clean bass sound.

 

There is a song I do that is downtuned which is just bass and vocals for the verse, this wouldn't work for that, its not an 'in the mix' song, it is effecgtively a solo bass sound, which the XE-1 can do.

Before folk start wondering, the XE sounds like an old Jag model to me? Time for a bit of Xmas XS? 😅

Oh yes, XS. Which sounds more like a Jag to me! What was wrong with PS - they have a PS-5 and 6, could this not be the 7?

[Al Krow]

I'm using the PS for +/- 1 and +/- 2 semis - works just fine! It struggles with +12 semis for octave up though which is where the "Overtone" fx comes into its own. Still not perfect or as clean as the dedicated Boss XS-1 for octave up, but certainly usable and the full patch, as outlined above, with amp sim and GEQ in the chain is a tasty tone thickener - very Fishman Powerchord!

 

Actually that kinda summarises some of the key pros & cons of the Boss multi-fx vs dedicated Boss pitch shift pedals:

• Boss XS-1: accurate pitch shifting without undue "flubbiness" for +/- 3 to 4 semis. A number of users have commented it's one of the best octave-up pedals around. But only able to do one interval at a time (albeit can mix wet and dry volumes). Whammy capability with external expression pedal. Couple of presets possible with external footswitch. Compact format.
• Boss XS-100: as XS-1 plus built in expression pedal for whammy-style effects. Multiple presets. Still only one interval at a time possible.

• GX10: decent, but more limited "usable" pitch shift range. Presets plus expression pedal can be assigned to any fx parameter. Fishman Powerchord tone thickening available with Overtone patch.

I was having fun with my GX-100 at lunch today. Managed to make a couple of fairly cool synth sounds with the bass harmoniser, bit of dirt, touch wah, guitar harmoniser, flanger/phaser, delay, shimmer reverb, vibrato, humaniser.

Parameter assignment

 

Nice YT review by this bassist who's a regular on Talkbass. Some really cool things to be done with parameter assignment, which is something I've just started scratching the surface on - was reminded of this clip by @MichaelDean's above post and I think Sean is using quite a lot of the same fx patches to build up his organ sound? I've started the clip at 06.22 in to dive straight into the relevant bit re. parameter assignment.
