Sei Owner's Club (Part 2)

Geez, Kevin. I feel so bad for you. I've been in that position in the past...



The other pre-amp that springs to mind would be Aguilar OBP-3, which is a bit of a wild card. Big, clear and clean sounding, though not exactly transparent and the bass control adds lots of big thick powerful bass (not the clear clean deep bass that I look for but liked by many).

...and there's the ACG/John East filter-based pre as well. I'm not usually impressed with electronics, but was knocked-out with this. Details at www.acguitars.co.uk
 
Kevin, very sorry to hear the news...

7 String, sorry forgot about the ACG/John East pre-amp though I'm not sure it's quite what pierreganseman wants (I believe it is not a traditional 3 band pre-amp that he said he was after). Worth considering though...I wondered about it for the SEI 9 string, but decided to go Audere instead.
 
I need some suggestions if you would be so kind !!

I have the Schack circuit installed in my Sei and I'm going to experiment with the DIP switches. With the switches on the underside of the cavity cover, it's going to be pretty tricky to set the switches then play the bass.

To save me a bit of time, I thought I'd ask on here what settings other Schack circuit owners are using for the DIP switches... or even if someone can suggest settings from the info below.

I think that the treble is set at 8kHz, the mid at 900Hz and the Bass at 100Hz

Thanks as always for any help you can give !!

Here's the Schack circuit details from earlier in this thread.

and here's the DIP switches in the bass. I've turned the photos that the gain pot (which i think is the vorvestarlung) is in the place as in the diagram.

7 String, happy to help but somewhat limited as I never had this circuit in any of my basses.

Everyone has their preferred tone control frequencies and there is little substitute to trying different frequencies to find your own preferences. My own conclusions over the years are:
  • Deep powerful bass - Typically 30-60Hz (enhances rather than modifies the original tone of the bass)
  • Bass - Typically 80-250Hz, with higher frequencies enhancing growl as much as bass (modifies the tone of the bass)
  • Mid - Typically 250-1KHz, all of which modify the original tone of the bass. Frequencies very commonly used include:
    • 400Hz - Harder, punchier more slap bass type of tone (stands out more in the mix)
    • 500Hz - Mid way, i.e. warmer than 400Hz & punchier than 800Hz (to my ears the best of both worlds and a firm favourite of mine)
    • 800Hz - Warmer, softer more jazzy type of tone (can get lost in the mix a bit)
  • Treble - Typically 2-5Khz with the higher frequencies adding more clarity (modifies the original tone of the bass)
  • Clarity / Sparkle / Presence - Typically 7KHz upwards (enhances the original tone of the bass)

Think about what changes you want your tone controls to make and then select the appropriate frequencies, remembering that tone controls typically work best when tweaking rather than transforming the original tone. I agree that your bass appears to be currently set up with bass at 100Hz, mid at 900Hz & treble at 8Khz.


Three other things you might want to do:
  • Set the mid frequency first (has the biggest impact upon the tone), then the treble and finally the bass;
  • Select max boost / cut to highlight the impact of the different frequencies;
  • Small changes in frequencies can be hard to hear, so I start with extreme settings and use the mid point between them to increasingly refine my selections until I can hear no difference (e.g. start with 500, 1Khz & 1.5KHz frequencies, then refine it to 500, 750 & 1KHz frequencies, then refine it again...)

Finally allow plenty of time and patience...it has taken me years to work out the above and my preferences. Also the very same settings may well sound different on different days and will of course sound different in different rooms/locations and also when mixed with different instruments. :bawl:
 
Firstly. where are BigRedX's photos !!!

Secondly, I altered the dip switches on the Schack 'board to 4kHz for the treble and 500Hz to the mids. This has had the effect of actually having a treble control that makes a difference and I managed to get rid of the awful mid tone that I had.

Thanks for the help Sei24bass. It's made a such a difference to the whole bass.
 
My baby has gone! boo hoo!!!

Actually - you have a really fabulous bass there - everyone who has seen it when I owned has raved about how incredible it looks - even people who know nothing about musical instruments have remarked upon how impressive it looks.

Really nice weight to it also, and lovely to play.

I am glad it has gone to a home where it will be appreciated - I hope you have many happy years with your new bass - and welcome to the Sei Bass club!!!!

here's some pics of it to keep you going for now

Firstly apologies for the lack of picture of my new bass but I haven't had the light to do it justice yet. Please be patient they'll be posted as soon as I have some worth showing off and believe me this bass is worth waiting for...

In the meantime pierreganseman congratulations on becoming a Sei owner, I had a play on that one while Martin was making the final finishing tweaks to mine, very nice to play indeed, and made me wish I could get on playing-wise with single-cuts instead of having to just appreciate their wonderful looks.

Yeah, i had many many frettless basses... kept looking for the right one. I think i have it now.

How old is it exactly?? :-)

cheers

don't worry it will be taken care of :-)
 
:) thx guys, don't worry, the sei will be well taken care of :-)

it does lookd amazing... for a moment i was thinking about asking martin to put fretlines on... i could not ask him... i think the piece of wood on the fretboard is too beautiful... would be a shame to put lines...

Sorry u had to sell it kevin...after less than 6 month...:atoz::rollno:

cheers guys
 
Finally... photographs.

The light was far from brilliant hence the poor depth of field on some of the shots but it the best I've had here all week. I'll take some better ones when the opportunity arises, but here at last for your viewing pleasure...

Er... YES - that's what a GREAT bass does for your playing - it's not cheating it's having the right tools for the job. Congrats Pierre on your new bass - so sorry you had to sell it Kev - and once again Red - huge congrats on the MOST stunning looking Sei - it'sa real work of art.

Thanks for the nice comments!

pierreganseman the top wood (and the back) is flamed sycamore double stained grey which is done by using a black stain on the bare wood and then sanding back until some of the unstained wood is revealed. Then the whole top is sprayed with a transparent grey. The masking required to do this caused Sims Custom quite a bit of extra work, but as you can see the results were well worth the effort.

Like yourself I've found my playing has improved with this bass. One of the things that has impressed me is how even the notes sound from string to string and some parts that on other basses had required big jumps up and down the neck can now be played more easily across the neck without sacrificing the tone of some of the notes.

I have my first band rehearsal with the bass on Wednesday. Looking forward to it immensely.
