Smile echo, reverb using bucket brigade delay lines from panasonic

hey everyone,

Ever worked with or used panasonic's bucketbrigade delay lines IC's for producing the effects such as stereo imaging , reverb, echo, chorus etc.

Attached are some of the schematics of using these IC's.

please comment if any body knows about them.


best regards,
Kanwar

If only you could find the chips. They've been discontinued long ago, and the guitar effects guys are desperately searching for last ones, paying even hunderd of bucks on ebay auctions.

If you could find some, you'll be rich...

Btw their sound is not good for hi-fi audio, they are somewhat slow, resulting in a noticeable high-frequency loss. Because of their warm sound, they're enjoyedc very much from guitar players...

I dont think that these are obsolete, because they are available here in INDIA at very cheap prices.
Any other substitute for these IC's for generating effects?

Remember the SAD1024? Those were hard to get but I heard they may be available again somewhere.

If all these chips are obsolete , then is there any alternative to produce sound effects with other methods. Any other chip which is not obsoleted yet?

Hi Giaime,
I'm around a lot! I may not post if I don't have anything to add.

Workhorse,
Don't know about the chips but you can always use a real reverb spring. No adjustment of time delay that I know of ....

Hi Chris! No I meant I hasn't been around a lot...

About the chips, nothing that I know can replace them. Since digital DSP all-in-one chips are so cheap (look at those guitar signal processor for 30$) there is simply no need for the analog real warm vintage (so many buzzwords!) bucket brigade delay chip...

Hi Giaime,
Okay, then welcome back! I though I saw some posts from you though.

Hey, I think I found your fuse. Shipping is a killer from here.
